BF2S Forums Full Screen Goddamnit!

So I was cleaning off my keyboard with an old rag while bad company was up on my computer at the main menu screen. Not my best idea. I guess I must have pressed a certain key combination to put Bad Company 2 into window mode, and now I cant get it back into full screen. Ive tried hitting keys, restarting my computer, double clicking the title bar, etc. Im out of ideas...
