Thanks. No loops or waits are in the scripts. It's really only a 
one-line "grab" command. However, I just sent him a revised staack that 
replaced "grab" with a repeat loop that sets the button to the mouseloc. 
That has the same symptoms; it doesn't work for him either. The odd 
thing is, some other butttons with exactly the same script do work for 
him. So it is intermittent.

He is running OS X with a gig of RAM, and Activity Monitor says he has 
513 megs free. That's more RAM than I have, so there must be something 
else going on. Besides not updating during a drag, he reports now that 
when he clicks a button that changes an icon, sometimes the icon doesn't 
change. But when he leaves the card and returns, the changed icon shows 
up. These buttons also all work okay for me on both Windows and Mac.

We are going to assume there is something wrong with his Mac unless 
anyone else has any ideas? I've never seen behavior like this, and I 
can't reproduce it here. Graphics card problem, maybe?
