Alt+Tab glitch (at least on steam version)

I had to tab out of Rimworld to find info about a problem I had with my mouse, and when I opened it again I couldn't click on anything but the music was playing. It seems like there is no way to exit it while being able to save. I tried unpausing using the space bar and after I did I could hear the sounds of the colonists working. So I think the graphics are just frozen, which is still a problem. I'm going to wait a while so it auto-saves, then I'll re-launch the game.

Turn of the run in background option! maybe this will help, it comes turned off by default!
