This is old news to some of you. In fact, I’ve known about this for many months now.
With the introduction of IE7, testing for IE6 compatibility issues has become a real pain. I would know — I encountered them when redesigning this site.
Anyway, there is a stand alone IE6 download at evolt.org which works flawlessly. Simply download the ie6eolas zip file, extract it, and run iexplorer.exe. It’s great.
