I hate mousedown

[Lynch, Jonathan]

Your're welcome!

The Drag stuff can get quite tricky. When the scripts are not set up
properly, it can cause your stack to freeze up, or to act as if there is
a script that keeps running and stopping in the background, causing
RunRev to act very sluggish.

For a button to receive a drapdrop, you need to have a script in the
button itself like this:

On Dragenter
  Set the acceptdrop to true
  Pass dragenter
End dragenter

This will allow the button to receive a dragdrop - I know this is
counter-intuitive.  You'd think that acceptdrop would be an object
property, so that you have a script that says

  Set the acceptdrop of button "my button" to true

But it is not set up that way, and that line causes an error.

Good luck,

Jonathan

Jonathan,

I did not know that at all. I haven't played with the drag stuff too 
many times. I am intrigued by it and am off to test some code.
It is sort of like faking the drag in order to make use of the other 
messages. Very cool.

Thank you very much,

Tom
