Might be best to ask in WoW Technical help forums; found here (http://forums.wow-europe.com/board.html;jsessionid=EC9F820132D17E03FA80C6B0E79C 7A44.app03_01?forumId=11079&sid=1).

If it worked find on xp and not on vista you might need to update some of your drivers.

Its because You are a Huntard + Vista sucks atm need to wait untill all the Proper Drivers are out

Might be that.
I have Vista and it works fine. I use full screen.
