Preview a web page in different versions of IE
I used Multiple_IE in the past when I wanted to test and verify something of my developed web app across browsers.
Today, I try to download the Microsoft Expression Web SuperPreview for Windows Internet Explorer, it is simply do the job correctly and also provide other useful features, such as change of screen resolution, details of DOM code etc.
If you need to preview a web page or test browsers compatibility (for IE only, not comparing with FireFox or Chrome), I'd highly recommend you to give it a try (and it's free).
