The global menu bar used by Unity is basically incompatible with the "Select windows when the mouse moves over them" option in "System" > "Preferences" > "Windows" (gnome-window-properties). This is because moving the mouse to the menu bar will often move it over another window.
So, whenever Unity is being used with the global menu bar:
* the "Window Selection" section of the "Window Preferences" window should be hidden
* the "Select windows when the mouse moves over them" option should be treated as if it was off.
