BlameThePixel!

I posted this as answers but i want to be sure that you will read.
I dont know iff you find the solution and i dont have the time to read all the forums. Excuse my english, i dont speack wreally well but i only try to help here.
When i instaled windows vista on my PC the game WWP stoped working properly. The resolution becomed 16 colors and reverted. After long searces i find the problem and the problem is that in Windows Vista, a new object called Desktop Windows Manager consumes most colour-efficient resources providing people the 'Aero' effect.
In most games, the 'Aero' effect in Windows Explorer won't allow necessary resources to run the game. And for that i foud this "FIX". It worked for me and i am gladfool to his creator, and i want to share this with other WWP lovers.
