I play in windowed mode using my monitor's native resolution (1920x1200) and occasionally - but not always - the Vista taskbar will remain on top of the game window, blocking among other things a part of the minimap. It happens totally at random and I've been trying to figure out the logic behind this - anyone have an idea why this happens only sometimes? Reboots or anything don't seem to have any effect. And yes I realize you can disable taskbar from showing on top of other apps, but I like it for browsing and such, and I'm basically too lazy to keep switching it on and off everytime I want to play civ. Using full-screen mode is hardly an option either since I just loooove that alt-tab!
