To start off, I'm on Mac OSX Mavericks. I have downloaded the game through the GOG downloaded as well.

I've been running into a seriously annoying bug. First off, whenever I load a new game (campaign missions and skirmish games alike), the screen flashes and shows all of the other windows I have open (usually iTunes/Safari, etc). That is not the major problem though. The annoying thins is that whenever I beat a campaign mission or finish a skirmish, the game forcequits before I even get to the mission results screen. Now this is pretty annoying in itself, but it also results in me having to change the setting every single time I boot up the game because I am unable to save my settings and any campaign progress.

Any idea how I can fix this? The actual gameplay works flawlessly, it's just that I am unable to save and all progress is lost whenever I finish a mission.
