This is a great tool for web designers (thanks Dan). For those of you continue to check out the compliance of your designed websites across multiple browsers, and possibly across platforms, be sure to check out ieCapture.

Here, you are able to see screenshots of how your pages will look across several browsers (ie 4-6. Firefox, Opera). Really neat.

And if you want to see how your pages will look on Apple’s Safari Browser, check out iCapture.
