Trapping for mouseDown on the desktop on a Mac

Ken,

I don't think you even need to go into a polling mode, as soon as user drags an item onto a stack it triggers a 'dragMove' message so trapping that should work on both platforms.

Tried a few tests with a small stack and tackling the problem from a different angle seems to do the trick on OSX and Win7.

Ray, the test stack is here, hope it helps… https://www.dropbox.com/s/hddd6qx0vmilsot/Drag%20and%20Drop%20text.livecode - no restrictions on use!

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.
