Trapping for mouseDown on the desktop on a Mac

Or another "polling" thing, if this helps at all:



on mouseUp
   checkForMouseDown
end mouseUp


on checkForMouseDown
   if the mouse is down then
      answer "Mouse is down"
      exit to top
   end if
   --doSomeProcess
   checkForMouseDown
end checkForMouseDown


Now when you run this and click in the finder, LC butts in because of the dialog. But you can do something else less obtrusive.

How about going into a polling mode, checking the dragData["files"] every second 
or so... it should start out empty, but as soon as the user starts to drag a 
file from the desktop, it should have something in it.

Just a thought,

reason, and this is a Mac-only behavior, when I mouseDown on the desktop I can't 
see any messages at all which are sent to Livecode.  The suspend message is sent 
if I mouseDown on another stack, but not on a file on the desktop or the desktop 
itself.

Should work the same on both platforms (famous last words!).

desktop click, thus defeating my scheme which creates the field to accept a 
dragDrop as soon as the mouse goes down on the desktop.
