(George Owen) asks if there is a way to tell if the pointer is in the menubar.

There's no message sent when the mouse pointer enters (or leaves) the menubar,
but you can write an idle handler to accomplish the same thing.  Try this one:

on idle
  global inMenuBar
  if inMenuBar is empty then  -- first time through
    put (the mouseV + the top of card window < 20) into inMenuBar
  end if
  if the mouseV + the top of card window < 20 then
    if not inMenuBar then
      send mouseEnterMenu to this card
      put true into inMenuBar
    end if
  else
    if inMenuBar then
      send mouseLeaveMenu to this card
      put false into inMenuBar
    end if
  end if
end idle

This will send a message whenever the mouse enters or leaves the menubar.  It
only sends the message once on each entry or exit (i.e. it won't continually
send the mouseEnterMenu message while the mouse is within the menubar), and it
initializes itself the first time through so no spurious message is sent even
if the mouse is already within the menubar.

I tested this, so I know it works.
