Hotkey for Torn-off Menu Causes Toolbar to Appear

I have made a torn-off menu and have assigned to it the hotkey Alt-N. When I hit Alt-N, the torn-off menu appears, but so does the entire auto-hidden toolbar.

In this case, the toolbar itself completely covers up the menu, unless the menu is set to Always on Top.

This needs a fix. The hotkey should not cause the entire toolbar to appear.

Thanks.
