Cannot close 'called' mGalaxy windows

[mgalaxy]

Have a look at your key mapping, in mGalaxy_Runway.
By default the '2' key (on the main keyboard, not the keypad) is used to exit all windows!

Everything works very well for me. The only real issue I'm having is that 'calling' a window for preferences/etc. makes that window unable to be closed without exiting mGalaxy.

I press Shift, or Alt, or any other called window button/key shortcut, and the window is up for good until exit of program.

Thanks. Maybe it's something I'm missing, but it's getting frustrating.
