Seems to me that this has not yet been answered.

You could try something like the handler below in the script of the 
dragged control:

"on mousedown
  set the layer of me to top
  grab me
  put the number of graphics into Gnumber
  repeat with i = 1 to Gnumber
    if intersect(me, grc i) then
      put the name of grc i
# or do whatever you want
    end if
  end repeat
  send "mousedown" to me in 100 milliseconds
end mousedown"

The last line does the trick.
