This works just fine, of course, for selecting the object. That is, until
you have, what was it?...30,000 of them. Then the loop will have the user
getting pretty long in the tooth before the clicked object gets selected.

You can, however, store the ID of the last object clicked, and just deselect
it when you select the next one. There is no loop involved. You can even use
one offscreen handler (subroutine) to do it, as well as whatever other
operations happen, even ones specific to the ID of the object, which is what
radio buttons are generally used for.

How about this:

on mouseUp
  RBbehavior
end mouseUp

on RBbehavior
  if i is not empty then
    set the selected of graphic ID i to false
    resetStuff -- maybe to graphic ID i?
  end if
  put the ID of the target into i
  set the selected of the target to true
  doStuff -- maybe to the target?
end RBbehavior
