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:
set the uAllowMove of me to true
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)))
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
else put empty
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?
