Unfortunately, I think the answer is "not much." I spent
the better part of a half hour this afternoon fooling
around with this, and I couldn't come up with a thing.
From the deafening silence, I'm afraid others are striking
out, too.

It probably goes against some GUI principle to allow
anyone other than the user to control the mouse, but
I guess I could think of one or two reasons why you
might have legitimate reason to want to do so. In any
case, unless I've missed something, I don't think it is
possible in object graphics. (Of course, you could put
an arrow or something inside a graphics windows and move
THAT around, but that isn't the cursor.)

Cheers,

David
