For example. You try to click on a browser tab but instead the menu bar just drops itself right overtop and you end up clicking on the menu instead. This makes Virtualbox at the very least, annoying, at the most unusable for any serious work flow.
I have found posts complaining of this issue 5 years old. I cannot comprehend how or why something this simple, and this annoying, would not have been corrected by now.
Details..
VirtualBox version 4.3.2
Host Machine MAC Book with OSX 10.8.5
Guest OS Windows 7
When I open VirtualBox > Preferences > General ..
uncheck the box.. Dock and Menubar (auto show in full screen)
Restart Virtual Box
Nothing happens. The top menu bar continues to show in full screen when the mouse is moved to the top.
