I have, yes. I'm running the game full-screen, so I can't drag the GUI. Is there a tweak somewhere that runs the GUI in a window while the main game is still full-screen?
Do any other multi-monitor XP 32-bit SP3 users have this problem?
Edit: Fixed. It anyone else has this issue, PM me. I'd detail how I fixed it, but I kind of stumbled across it after experimenting, and I'm too tired to retrace the steps in detail. Basically I forced the GUI to always be windowed, and always have 1/2 the horizontal resolution of the desktop.
