When in a terminal window, right-clicking often opens a new terminal rather than displaying the menu. (I'm not sure if this is because of where I click, or if I'm hitting another button, or something else -- but it happens often, maybe 5 times a day.)
Is there a way to disable this behavior?
(I'm not sure what causes this, exactly... Metacity? GNOME? I don't think it's the shell itself.)
