Anyone help me?? while i'm playing, if i click anywhere away from the window i'm playing TB in everythings fine, but then when i click back to the TB window about 2 inches from the right hand side of the window just turns into a solid white collum. its really annoying on the multiplayer version, and this happens even if i try to change to fullscreen mode,
thanks
Elfie

What graphics card do you have ?
Try to minimize and restore.
