Comment 40 for bug 674138

From what i've read on this problem the only simple solutions that i see are:

 1. As others have suggested, have an option to show the menu in the window when not maximized.

 2. Give the option to wait a little (200ms - 500ms) before changing focus to another window. This gives plenty of time to move the mouse to the appmenu on the top from any position on a big screen. The focus change delay is so small that it'll be imperceptible for most of the users.

I personally, would prefer option 2.
