Try to ignore the fact that this post is about a Microsoft tool. After my rant about how Microsoft people are horrible, anyone reading this is probably a bit perplexed about the title.
To make a long story short, I got a new laptop, and it came with Windows 7.
I am working on deploying live chat software for a client, and despite my hatred of Internet Explorer, more than 50% of the world's population still uses it, and it's up to me to put aside my personal distastes and make my clients' happy.
I found a bug in IE7 using IECollections. Generally, when I find IE bugs that I can't seem to immediately find the answers to, I figure it's just caused by the fact that I'm not using a real version of IE7. I spent over an hour trying to find someone in the organization who had IE7 installed, and another 20 minutes trying to get a screen share started to verify that we were really looking at IE7.
Well, after stumbling around Webmasters Stack Exchange, I found this question about How to Test IE7 on Windows 7. It turns out it's very simple. That link will show you a picture that will speak a thousand words. Go ahead, check it out!
