There are some games like Team Fortress 2 that allow you to access all your Expose actions and Command+Tab while in-game (full screen). But then there are others like Call of Duty 4, which only allow Command+Tabbing, or a game like Savage 2, which has you completely in the game, no Expose or Command+Tab ability. What is happening in games that take away the ability to use Expose and Command+Tabbing? And is there a way to get around it? Thanks.
