Well its weird my screen is stuck in the top right corner and I can not move it.
I think I grabbed it at the lowest pixle and then moved it.

I can't reach the bar in which you can move the game with XD
Just quit and log back on.

Heh, I did that once- except I dragged it below the start bar almost. I had a pixel above it, but you can't drag with that... Anyways, I think there should be a button which centers the screen.

Just right-click the task on the taskbar, click move, and then use the arrow keys. That should work ;)
you can try to restart or rez your screen down a little an bring it back up. There probably easier ways i cant think of now.
