I am a huge fan of skinning my pc but i am also an avid gamer.  Lately i have been getting this message in my games that use punkbuster

Unknown Windows API function (131152)

Took quite a bit of research on different sites but it appears from everything i have read that windowblinds and the latest update of punkbuster may not be 100% compatable.

to solve this  go back to your default xp/vista desktop, sometime i hear excluding the game from skinning works as well.
