Why is FarCry 2 running in windows mode?

[GJohn]

And i cannot find an option to disable it...

I had probably the same issue where if I alt tabbed, there was no way i could make it go back to fullscreen and it stayed in windowed mode

you'll have to go into my documents/my games/ far cry 2/

and open GamerProfile.xml with note pad

edit the following:
Fullscreen="1"

in the case when it's always windowed, the 1 will be a 0 so change it to a 1

Alt+Enter fixed it right away, thanks anyways.
