Not so simple.  After a short while, the arrow returns.

Attached below is a simple little routine written by Mark Colburn
(mark@jhereg.mn.org ... credit is given... :-) which will toast the
arrow.  

To make the arrow go away, move it into the main window and run mouse.
If you leave the mouse in it's default start position and run mouse,
the arrow won't go away until you move it into the window.  This is
all I needed it to do, so that's as far as it went.  At least it's a
start if anyone wants to add to it, and if they do, please send it
along.

We thank you for your support.  :-)
