   5 # 11/30/2003 - Jeff Grimmett (grimmtooth@softhome.net)
   6 #
   7 # o Some issues with the listbox example; I tried correcting
   8 #   it but it's still not working the way it should. Commented
   9 #   out for now but will be revisited.
  10 # o The math in determining the popup window's position is
  11 #   a bit off.
