Pretty minor problem in the scheme of things, and I know there are much higher priority issues, but it would be nice to see it fixed eventually. I play in full-screen mode at my max monitor resolution (1680x1050). When I alt-tab out and back in, the game changes from full-screen mode to windowed mode. Unless there's an option I'm not seeing, the only way to get it back into full screen mode is to save the game, close it down, then relaunch and click "Full-screen" when it launches. Effectively, to stay in full-screen mode, you pretty much need to save and close any time you'd like to alt-tab out. In case it matters and this isn't an issue other people are having, I'm running Windows 7 64-bit.
