Install multiple versions of IE on your PC
This useful app allows you to run different versions of Internet Explorer on the same Windows install, which sounds pretty clever and indeed it is. A simple download and install and it seems to do exactly what it promises. Now why can't Microsoft provide that kind of functionality, I wonder?
I also tried the IE7 standalone install but I can't tell how successful that's been yet. IE7 started up just fine, but the first dropdown I tried to interact with throw a 'popup blocked' error. Could be a glitch but I can live with it for now.
