I select mouselook, (for instance typing 'm') (after this point I have no cursor) I select Apple's minimize window (by typing command 'm') (this is a natural error or possibly an intended action) It is a likely mis-step if I intend to exit mouselook. At this point I have almost no control over my machine. I have neither keyboard nor cursor with which to act. The viewer seems to consume all input yet not respond. If I am very savvy I know an obscure way out of this box: 'command-option escape' then return return. This runs the 'Force Quit' software function built into the Mac. Few users have learned this back-door to Force Quit.

I think that a Mac application is informed when its window is minimized and that it should temporarily reinstate the cursor. I think too the the Mac OS should do this by itself.
