On first sight, this probably sounds daft given how good Firefox is but you cannot ignore those surf the web using the ever pervasive Internet Explorer when doing some web development. Using virtualisation is a solution to the need but it can mean that you need to set up a web server with Perl, PHP, MySQL and the like in a virtual machine, all for a little offline testing and then there’s the potential for a lot of file copying too. Otherwise, you are trying to sneak things online and catch the glitches before anyone else does, never a good plan.

Therefore, having the ability to run IE to test your offline LAMPP set up is a boon and IES4Linux allows you to do what’s really needed. Naturally, WINE is involved so some flakiness may be experienced, even after the ever useful API library’s reaching version 1. Otherwise, all usually runs well once you work you way through the very helpful instructions on the IES4Linux website. I did get a misplaced message about the version of WINE that I was using and Python errors made a worrying appearance but neither compromised the end result: a working IE6 installation on my main Ubuntu box.

IE5 and IE5.5 are also on offer if you’re interested but, after looking at my visitor statistics, I think that I can discount these. IE7 and the work-in-progress IE8 make no appearance on the availability list. The absence of IE7 is not a big problem as it might appear because coding for IE6 sufficiently suffices for IE7, even now; IE8 may not be the same in this regard but we shall see. Even so, a later browser release does mean a more secure version and I reckon that including IE7 should be next on the project’s to do list. Saying that, what we have now is far better than nothing at all.

It’s quite hard to describe this observation in a title so here goes with a longer description in a post. One thing that I spotted with the Prosumer theme used on this blog is that the links on the horizontal navigation bar underneath the mast head were not appearing as they should. The links have been formatted using CSS to appear in boxes with borders that are more apparent when you hover over them. In IE, the top and bottom borders were missing. After a spot of digging, I came up with the line-height property being the cause and I was right: the extremities of the boxes surrounding the text were being cut off because they exceeded the allotted space. As if to emphasise that IE7 isn’t as major a leap forward from IE6 as we would have liked, the problem affected that browser as well.

Aside: Link text colours weren’t being honoured by IE7 like they are by IE6, Firefox and Opera so another tweak to the CSS was needed.

Looking through Google Analytics for my websites, I have always been struck by the lack of IE7 uptake seemingly apparent from the statistics. However, I recently discovered that there may be a reason for this. I use the Ultimate GA plugin with my WordPress blogs and that adds the JavaScript code block near the bottom of the page. However, I recently saw that giving me scripting errors in IE7 and a spot of manual coding saw it travel to the header section of the web page. That, and the deactivation of the said plugin, was sufficient to rid of the errors in question. Seeing the effect of my changes on the reported share of visitors using IE7 could be interesting. It might even boost the Vista numbers as well.

Having been exposed to an application at work that uses a lot of JavaScript, I fully appreciate what some mean when they talk about IE6’s inefficient handling of JavaScript. After seeing a web page taking an age to reload and your CPU taking a hammering because of JavaScript processing, the penny does tend to drop… Needless to say, this very much impacts the world of AJAX-driven web applications with their heavy dependence of client-side JavaScript. While IE7 does come to the rescue, there remain plenty of IE6 users still out there and this is reflect in website statistics. This reflects a certain level of inertia in the browser market that not only afflicts the uptake of IE7 but also the likes of Mozilla, Opera and Safari. It also means that anyone developing AJAX applications very much needs to continue testing in IE6, especially if the product of their labours is for wider public use. An example of such an application is Zimbra, an open source web application for messaging and collaboration, and the people behind it have generously share the results of their browser performance benchmarking. They did comparisons of IE6 vs. IE7 and Firefox 2 vs. IE7. IE6 easily came out as the worst in these while Firefox 2 was the best. I suppose that the next question to be asked centres around the type of code that is processed inefficiently by IE6. I wouldn’t be at all surprised if a list emerged but here’s one: using Microsoft’s proprietary innerHTML object to update the DOM for a web page format. Having a quick trawl on Google, this came up for mention as a cause of memory leaks. It is also a Microsoft innovation that never got taken up by those overseeing web standards, hardly a surprise since a spot of DOM scripting achieves the same end. It may be faster to code than any alternatives, and it does have some support from other browsers, but it does seem to have got a bad name and so should be avoided if possible. That said, it would be interesting to see a performance comparsion between innerHTML and DOM methods in IE6.

My installation of Firefox seems to have stopped listening to the target attribute of hyperlinks. Thankfully, the middle mouse button comes to the rescue. Clicking on a link with the middle button opens it the destination page up in a new window or tab, depending on how you set your defaults. The behaviour goes even further than this: the trusty middle mouse button does the same for bookmarks and the Google search bar; all very useful. And its not just a Firefox thing either. IE7 does the same thing for web page hyperlinks and bookmarks while in Opera, it is limited links on web pages.

With its imminent launch and having had a quick at one of its beta releases, I decided to give Office 2007 a longer look after it reached its final guise. This is courtesy of the demonstration version that can be downloaded from Microsoft’s website; I snagged Office Standard which contains Word, Excel, PowerPoint and Outlook. Very generously, the trial version that I am using gives me until the end of March to come to my final decision.

And what are my impressions? Outlook, the application from the suite that I most use, has changed dramatically since Outlook 2002, the version that I have been using. Unless you open up an email in full screen mode, the ribbon interface so prevalent in other members of the Office family doesn’t make much of an appearance here. The three-paned interface taken forward from Outlook 2003 is easy to get around. I especially like the ability to collapse/expand a list of emails from a particular sender: it really cuts down on clutter. The ZoneAlarm anti-spam plug-in on my system was accepted without any complaint as were all of my PST files. One thing that needed redoing was the IMAP connection to my FastMail webmail account but that was driven more by Outlook warning messages than by necessity from a user experience point of view. I have still to get my Hotmail account going but I lost that connection when still using Outlook 2002 and after I upgraded to IE7.

What do I make of the ribbon interface? As I have said above, Outlook is not pervaded by the new interface paradigm until you open up an email. Nevertheless, I have had a short encounter with Word 2007 and am convinced that the new interface works well. It didn’t take me long to find my way around at all. In fact, I think that they have made a great job of the new main menu triggered by the Office Button (as Microsoft call it) and got all sorts of things in there; the list includes Word options, expanded options for saving files (including the new docx file format, of course, but the doc format has not been discarded either) and a publishing capability that includes popular blogs (Wordpress.com, for instance) together with document management servers. Additionally, the new zoom control on the bottom right-hand corner is much nicer than the old drop down menu. As regards the “ribbon”, this is an extension of the tabbed interfaces seen in other applications like Adobe HomeSite and Adobe Dreamweaver, the difference being that the tabs are only place where any function is found because there is no menu back up. There is an Add-ins tab that captures plug-ins to things like Adobe Distiller for PDF creation. Macromedia in its pre-Adobe days offered FlashPaper for doing the same thing and this seems to function without a hitch in Word 2007. Right-clicking on any word in your document not only gives you suggested corrections to misspellings but also synonyms (no more Shift-F7 for the thesaurus, though it is still there is you need it) and enhanced on-the-spot formatting options. A miniature formatting menu even appears beside the expected context menu; I must admit that I found that a little annoying at the beginning but I suppose that I will learn to get used to it.

My use of Outlook and Word will continue, the latter’s blogging feature is very nice, but I haven’t had reason to look at Excel or PowerPoint in detail thus far. From what I have seen, the ribbon interface pervades in those applications too. Even so, my impressions the latest Office are very favourable. The interface overhaul may be radical but it does work. Their changing the file formats is a more subtle change but it does mean that users of previous Office versions will need the converter tool in order for document sharing to continue. Office 97 was the last time when we had to cope with that and it didn’t seem to cause the world to grind to a halt.

Will I upgrade? I have to say that it is very likely given what is available in Office Home and Student edition. That version misses out on having Outlook but the prices mean that even buying Outlook standalone to compliment what it offers remains a sensible financial option. Taking a look at the retail prices on dabs.com confirms the point:

Office Home and Student Edition: £94.61

Office Standard Edition: £285.50

Office Standard Edition Upgrade: £175.96

Outlook 2007: £77.98

Having full version software for the price of an upgrade sounds good to me and it is likely to be the route that I take, if I replace the Office XP Standard Edition installation that has been my mainstay over the last few years. Having been on a Windows 95 > Windows 98 > Windows 98 SE > Windows ME upgrade treadmill and endured the hell raised when reinstallation becomes unavoidable, the full product approach to getting the latest software appeals to me over the upgrade pathway. In fact, I bought Windows XP Professional as the full product in order to start afresh after moving on from Windows 9x.
