Here's another technique for identifying the object at the mouseLoc. This
technique is different because it works with no repeat loop, no checking the
visible or the rect of any object, no formulas based on the mouseLoc, and no
reference to the mouseControl.

Create a button named "mouseObject" with the following script:

-- <script>
local sMouseObject

on mouseObject
  if line 1 of the frontscripts is not long id of me then
    insert script of me into front
    lock screen
    click at the mouseloc
    unlock screen
    remove script of me from front
    return sMouseObject
  end if
end mouseObject

on mousedown
end mousedown

on mouseUp
  put long id of the target into sMouseObject
end mouseUp
-- <script/>

Then to test it, put the following handler into the stack script:

-- <script>
on mouseMove
  call "mouseObject" of button "mouseObject" of me
  put the result
end mouseMove
-- <script/>

The technique passed my tests.  Does it work for you?
