This menu is not always there. This behavior adds errors because, if you move up too high while using the menus, the top menu drops down and obscures your bottom menus. This forces the user to release the mouse button, and try to hit their target again. But that error only happens if you are using the menu's by holding the mouse down. Which brings us back to inconsistent.
Some menus behave different than others, sometimes.
One control closes the document, the other exits the program. Notice the proximity of the CTRL and ALT keys to each other. So trying to shortcut one, is likely to result in the other. This will increase confusion and accidents. You might as well just use the mouse.
