Messed Up My Crysis Install

[dmw16]

I was playing Crysis and accidentally hit one of the buttons on my mouse that launches some stupid search box in windows. It caused Crysis to minimize. I exited and restarted and now the game runs with the "window box" around it and it runs very slowly.

I tried restarting windows and it still does it. What did I do? How do I undo it?

Press Alt-Tab and see if it makes it full screen again.

go to the graphics section of options, check "play full screen"

Alt-enter is the shortcut for full screen/windowed.
