I played Dirt 3 for the first time and after playing for a while i tabbed down with alt+tab and then when i tabbed up again my fullscreen was gone so i went into the graphic options and changed the resolution many times but it still wasn't full-screen :S What should i do? (I have Windows 7 64 bit home premium if that is rellevant) There is no "full-screen" option in the graphic options by the way...
