I still have a _very very annoying_ display bug which occurs when a menu item causes a submenu to be displayed - the screen repaints for the original menu (which is restored upon return from the submenu) are off by about 4 characters. I've tried restoring the screen, the cursor position, you name it - same deal. Grrrr! This commit is my first step in trying to get someone else to help me look into this one since I'm just tearing my hair out at this point!
