I have downloaded the latest beta v3.05 and it seems actually working.
Note that 3.05 is not publicly released yet, but you can download it here:

With this, and Multiple_IE (http://tredosoft.com/Multiple_IE) (thanks to TredoSoft) I can test my pages in IE 5.5, 6.0, 7.0, Firefox and Safari in single PC :agree:

Are there any statistics out there about how many people are using IE 5.5 and Safari (not together of course)?
I'm using Multiple IE too but just for IE6.0. Great and handy.

Safari's implementation of ECMA standards is almost as bad as IE's interpretations of HTML standards. I hope they're working on this in Safari, because it's the #1 reason I put it only slightly ahead of IE in terms of its usefulness. I'm not impressed by Mac's browser - I've never much cared for it.
