Added the notion of a 'cancel' button, and unified all the 'cancel' menu IDs to be kCancelMenuID (ie -1). I've slaved the Menu button (ie Esc on win, 'Start' button on PSP) to this - the idea being, if you hit the Menu button to bring up a menu, hitting it again will dismiss it without doing anything, which is pretty standard behavior for most console/computer games.
