Thanks for the report Cheetah, I sent you a pm with some questions.
I'll deactivate the dl for 1.0.8 osx version until I've figured out the issue.
Edit: Okay so if I understand- it was the fullscreen mode that was giving you trouble. I had the fullscreen key disabled, and I didn't think anyone would be able to get into fullscreen mode, but perhaps that is not the case on a mac. So I have enabled fullscreen key(f11), and I also made the Esc key for quitting(it should still ask if you are sure you want to quit).
Hopefully this will solve the issue of becoming stuck in fullscreen mode.
v1.0.8b is available.
edit: also changed a window setting in osx version- so it should show up in dock now.
