Unfortunately my feeble attempt with:

on mouseDown
   grab me
end mouseDown

on mouseStill Down
    if the loc of me is within the filled of graphic "XXX" then
      put "inside" into fld "INN"
    else
      put empty into fld "INN"
end if
end mouseStillDown

resulted in no joy as THE FILLED was invented by me :(

and, of course, 'the rect' is no use at all.
