I installed IE7 at work a while ago. Worked just fine.
So this weekend, I was feeling frisky and I installed on my main home computer. Whoops. Now IE crashes every single time I hit a web site. Its junk. Nothing works. I disabled all the toolbars I had. No better.
I also installed the release candidate for Firefox 2. IE is a release candidate too. Firefox works well. Maybe its time to change my default.
