How to run the game in a window:

From the main menu, click "Preferences", then "Video Preferences". Then uncheck the "Fullscreen" option at the top.

If you then maximize the window, it's almost like having it full screen only much more convenient (a lot easier to check e-mail and so on or look at other things while the turn's processing). Since I discovered this option I've had it windowed the whole time.
