I just upgraded to Mountain Lion and both the single player and multiplayer version of COD4 are no longer in full screen mode. I looked at the 2 config files and the fullscreen variable is set to "1." Is anyone having this problem and ideas on how to solve it? This is pretty much the only game I play on the Mac and it's frustrating to see it broken. If there isn't a solution, my next question will be how do I go about downgrading! (Kidding, of course..) All help is appreciated. Thanks.
