Another way to do this would be to place the following script in a button or
graphic in your stack.

on mouseDown
  set the uAllowDrag of me to the clickH & "," & the clickV
end mouseDown

on mouseMove x,y
  if the uAllowDrag of me is empty then exit mouseMove
  put globalLoc(x&","&y) into tLoc
  set topLeft of this stack to \
      item 1 of tLoc - item 1 of the uAllowDrag of me,\
      item 2 of tLoc - item 2 of the uAllowDrag of me
end mouseMove

on mouseUp
  set the uAllowDrag of me to empty
  # YOUR TRAP SCRIPT HERE
  answer "The drag is done."
  #
end mouseUp

on mouseRelease
  mouseUp
end mouseRelease
