I haven't been following this topic, but here's the approach I would use for telling single and double clicks in Hypercard (plus a mouseDoubleUp check to see that it didn't get through:

on mouseUp
   wait 20
   if the mouseclick then
      put "double click" && the ticks
      put "single click" && the ticks
      end if
end mouseUp

on mouseDoubleUp
   put "double up"
end mouseDoubleUp

If you comment out the wait line, you'll see that the double up handler gets called.
