D minimises UT3 back to Desktop! WTF?!?

make sure you didn't bind your keyboard's d key to something in the keyboard's driver software, if you have any.
I think there's a glitch with windows sidebar when it exits that can sometimes cause keyboard/mouse drivers to not work correctly. Logitech anyways. I was hitting f1 and it was using a special function the keyboard has built in instead of sending f1 to the game.
then make sure u didn't bind it to anything in the in-game/.ini keybinds.

Did you try alt+enter = exit full screen/enter full screen

Maybe your windows key is sticking ? Win key + D = desktop

Hi, I have a bit of a problem. Seems I can't play anymore because all of a sudden whenever I hit the 'D' key my game gets minimised and I'm looking at my desktop.
The last couple of games prior kept crashing due to duplicate logins and now this.
I have a legit version of the game. Any suggestions on what I can do to get playing again?
