Half Life 2 always run fullscreen and took up all the window space...for some reason now it runs fullscreen, but doesn't take up the whole screen. There is a black border around the 'HL2' game window. This is very annoying - I've chaged the desktop resolution and also the one in HL2. If you change from 4:3 to 16:9 itn HL2 it used to take up the whole screen, now it just flicks between a square and a oblong in the middle of the screen. Also I get an ATI message on startup stating that I have TV mode enabled and that I should disable it...with no way to do this. EDIT: All games run in this window...Max Payne 2 also runs in a small window....any ideas?
