I downloaded this to my home computer about 10 days or so ago. It refused to work. It would not start. Every time I tried to start it, it would immediately crash.
I decided to try again on a computer at work, which also runs WinXP Pro SP2, just like my home computer. It ran fine. However, I noticed that some menu bar options on vBulletin message boards were different between IE6 and WinSafari. Specifically, the drop-down menu bars (like Search and Quick Links) were gone, replaced (if I recall correctly) by a simple Search link and some other links like Mark Forums Read (some of the links from Quick Links). However, in the real Safari on Mac OS X (incidentally, what I am working on right now), the vBulletin menu bars are the same as in IE6/IE7 on Windows.
