I get exactly the same thing.If you alt , tab to the desktop and back it fixes it.Not a great solution but it works.Does your mouse allow you to use the wheel to scroll the action menu?.It used to work in ME so it must be an XP problem.

Not sure if this will help but I was having all sorts of problems with my geforce 2 pro with those new XP 4 in 1 drivers.All my games where stuttering until I used the XP feature to roll the geforces card back to the GTS drivers windows xp originally installed.Games appear to be a lot smoother although I havent fully tested this assumption yet. On another note can we not jump to the conclusion that the only way to fix small issues is to spend a fortune on upgrading your PC every time ,its so unhelpfull and its not gonna happen.Sorry to all the genuine helpers out there but it really makes my blood boil.
