Since alt-tabbing the game yesterday they game has bene running in windowed mode, and i cannot maximise it. I am running windows vista. on the top tab of the game ( minimise, maximise, and close) maximise is "blacked out" and so i cannot selesct it, nor when right clicking. I have encountered this problem before with crysis, but it had a windowed box that i just had to re-check... your help would be appreciated.
