I'm trying to pop another stack with selections over an object from that
object's handler.  My concern is the popup going over the top or bottom.
 (There's a secondary left/right issue, too, but the top/bottom is the big

So something like

on mouseOver

lock screen

palette stack "choose" at the screenLoc of me

do some magic to keep it on screen

end mouseOver
