Vista - starcraft crashing problem

heres my problem, when i play any game, whether its online, the campaigns, or custom games, ill play the game and everything is fine, up untill the game is over like when i win, die, or it comes to a draw

as soon as i click the "victory" buttom (or w.e button is there), it gos to a black screen and quits working. I here the error sound but no error pop up.
i have to click ctrl alt delete to get out of it. when the black screen gos away i am greeted with my desktop being multi colored and realy big to where it doesnt fit the screen.

anyone know how i can... well... fix this?
man vista realy doesnt like the classic games
