this will only chew up processor time, checking many times a second.  what
youneed to do is when the user clicks on a close box, call TrackGoAway,
then if true, check if it is yours or a DA's.  if a DA's, dim the Edit menu
and call CloseDeskAcc.  for other cases, dim the Edit menu when your
windows are activated, and undim it when they are deactivated.
