When I booted the game up this morning, all of a sudden I discovered that, after a short period of time, I couldn't scroll the screen using my mouse. The problem corrected itself when I entered a menu and went back, it fixed itself...only to un-fix itself later. At first I thought it was whenever I entered a new room, but then I discovered that just waiting around for about ten seconds would work just as well at causing it to start up again. I can still move my guys around, and I can still scroll using the keyboard, but when I move my mouse to the edge of the screen, the cursor doesn't turn into an arrow. It just stays a pointer.

I've never heard of any problem like this. I checked the option menu, but nothing jumped out as a possible fix. And this wasn't happening yesterday, of that I'm certain. Does anyone have an inkling as what the problem may be, and how to fix it?

I don't currently have the fixpack installed (I didn't know it existed until I was pretty far into the game), but, that said, I really hope that the answer isn't "install it", because I really don't want to have to re-start my game file.

If it makes any difference at all, the last place I saved when things were still working normally was the Modron Maze foyer.
