I don't like to waste screen space, so usually I have the menu bar hidden. Sometimes, I'd like to show it nevertheless, so I have bound the "menu" key to menu-bar-mode. Works perfectly:
(global-set-key '[(apps)] 'menu-bar-mode)
My emacs window is always maximised. That's no problem when showing the menu bar. But when I hide it again, the window is not maximised any more. It is resized and the height of the menu bar is missing :( Is there a way to prevent this?
To make it more complicated: I'm talking about native windows Emacs (GNU Emacs 24.5.1 (x86_64-w64-mingw32) of 2015-05-16 on KAEL)
