Microsoft's release of IE7 has made my life difficult. In the past I would develop a site and check it out in Firefox and IE6 to make sure all was well. I've yet to install IE7 because doing so will clobber my installation of IE6. I don't want to lose IE6 because I want to be able to test my code with that browser which an awful lot of fools people are still using.
Not installing IE7 has created another problem. How do I test my code in IE7 if I can't have both IE6 and IE7 running on my pc? I can have multiple version of Firefox, but only the one version of IE. I just came upon this IEBlog entry about running IE6 and IE7 on the same computer. They recommend running IE6 in a virtual instance using their Virtual PC. There are links on that page, if you've got the same issue I do.
One more thing. Get Firefox and the entire issue becomes moot. Thanks.
