If I understand your request, this is one way you could do the above.  Make
3 small graphics named box 1, box 2 and box 3 within the region you define.
Then place the following script in your oval:

on mouseDown
  set the uAllowMove of me to true
end mouseDown

on mouseMove x,y
  if not the uAllowMove of me then exit mouseMove
  set the loc of me to (max(81,min(557,x))),(max(167,min(287,y)))
end mouseMove

on mouseUp
  set the uAllowMove of me to empty
  put "box1,box2,box3" into bList
  repeat for each item B in bList
    if within(me,loc of grc B) then
      put "You found box" && B
      exit repeat
    else put empty
  end repeat
end mouseUp

on mouseRelease
  mouseUp
end mouseRelease

-----

This should display the name (in the message box) of any box graphic that
falls within the oval when the mouse is released.

BTW, did you look at the drag example I posted a few days ago?
