Wierd graphics is Windows XP

[greyuriel]

I've disabled the day/night graphics and now when I close the game the graphics in Windows are smashed to the top half of the screen, but I still have to use the whole screen for the mouse. I restart WinXP and everything is fine.

Re-enabled day/night. Closed the game. Still acting weird.

Restarted game with option enabled and closed again. Everything fine.
