IETester is an indispensable tool when debugging css or javascript. It have all
the rendering and javascript engines of IE8 beta 2, IE7 IE 6 and IE5.5 in one nifty package.
I used to rely on IE7 and a standalone version of IE6 for my testing, as Windows makes it hard to have more than one instance of Internet Explorer on the system.
I didn’t want to break a working environment to install the beta versions of IE8, with this tool I can finally do some testing and see what IE8 is good for. IETester works on both XP and Vista, it is still an alpha so there is some bugs.
