robust. The new "fire" actions, while affording signficantly more interactivity to libdialog, come at a cost - if the fire action trashes the screen then you're not going to be in Kansas anymore when you come back to the menu and there had better be considerable extra smarts in place for coping with such a situation. These changes are my attempt to do just that.
