Where do I toggle whether or not the top menu bar of a window appears? I've currently got five windows, and the menu bar only appears on one of them. I haven't changed any settings concerning the menu bar at all that I'm aware of, so I'm not sure how that happened. :)

Open the window(s) in question, edit them (by double clicking on their background, or right-clicking and selecting "Edit [window_name]..."), go to the "Options" tab, and set their "Menu ID:" to the menu you want shown, or blank for none.
