When it launches, it goes full screen. Because of that, the screen goes black and I can't do anything with the computer except shut it down. If you tell me "Ctrl, Alt, Delete" or "Press Esc" I will wring your neck.
Added (1). Thanks, Lenyung. But first it shows the Mojang logo, then goes full screen, leaving me with a black screen. Pressing F11 doesn't work either.
I think it's something with the display, because the game still runs. I know because I can hear the music that always plays at the title screen.
