DX GOTY constantly minimizes to taskbar

[Colonel Panic]

I keep running into this. Every time I start up the game, it plays the first one or two seconds of the intro, then minimizes to taskbar. If I bring it back up, it just minimizes again.

Since I'm playing the steam version, I cannot run in compatibility mode or anything that requires administrator rights, or the game won't see steam, and won't launch.

I've tried using the d3d10 renderer for it, but I can't even get far enough into the game to activate it in the settings, so that's out.
