For years I've been meaning to download and install a program that allows multiple IEs to be used for testing web design/development. Does anyone have experience with these - or use virtualization to achieve the same thing?
Treadsoft's Multiple IE - around for years, but doesn't allowing test on IE7 and IE8
Edskes Software's ("Internet Explorer Collection") - looks too good to be true ... IE 1 through IE8!.
IETester - buggy, some crucial features have problems.
Virtual desktops have also been recommended
