Anyone know any working windowed mode?

I would like to minimize combatarms fast without it crashing 50% of the time, does anyone know a working windowed mode for ca, if so it will help me greatly, thanks.

Edit: woot no responses.....

i dont noe of any wrking windowed modes. i once tried one and it wrked, till i joined a game. in lobby, it was in windowed mode. then when i joined a game, it went full screen.
i run windows 7 ultimate 32 bit btw

the next best thing to windows mode is alt+tab. it minimizes ur game. or do u already do tat? does it crash ur game?
