Here's what worked for me (put this in the card script):

global gDragging

on mouseDown
  if word 1 of the name of the target is "button" then
    put true into gDragging
  else
    pass mouseDown 
  end if
end mouseDown

on mouseMove
  if gDragging and the mouse is up then
    send "GetTarget" to me in 20 milliseconds
    put false into gDragging
  end if
  pass mouseMove
end mouseMove

on GetTarget
  try
    put the short name of the mouseControl  -- or anything else you 
want to do with it
  catch tError
    -- it would get here if you released over the card itself
  end try
end GetTarget

Hope this works for you...
