keymapping unusual behaviour

when I press opt, the key mapping can't work properly. I then try cmd+K to edit key mapping but can't close the editing page with cmd+K. then I try to close key mapping editing with the top bar and after that I can't find my mouse and can only click the mouse button.

Should have been fixed by #83. Try a recent nightly version and see if it got fixed.

I am using playcover2.0.4 and playtools2.0.7
