put this transcript in the button script of a button with submenus and
cascade menus

on menuPick theItem
  put theItem & "  " & the menuHistory of me
end menuPick

this will show that cascade menuItems as well as menuItems can get a message
sent and intercepted ... so this handler should be able to toggle the
checkMark of any selected menuItem and cascade menuItem
