Trapping for mouseDown on the desktop on a Mac

[Ray]

Phil,

Many thanks for including this stack!  I'm in New York right now (out of 
town for me) but I'm anxious to get back home in a few days where I can 
experiment with this on my Mac.  Interesting how you've put the scripts 
in the card script but still need the field present to catch the 
message.  What I'd like to see is a stack with absolutely no objects in 
it receive the dragDrop message somewhere, either in the card script or 
the stack script.   But evidently we need to put 'dummy' controls like a 
field or an image on the card to trap for this message.  Please correct 
me if I'm wrong.

Thanks,

Ray

For some 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.

I use this to create a field which then accepts dragDrops.  However, this is different on a Mac.  The current stack window on a Mac waits until the mouse comes up on a desktop click, thus defeating my scheme which creates the field to accept a dragDrop as soon as the mouse goes down on the desktop.
