thank you, derek...

=This is correct as far as it goes.  But there is a legitimate need to reset
=the revised desktop when the program has been called from a shell.  Otherwise,

thank you, bob. yes, i found this undocumented trick out in the last atari
developer's newsletter. if allan's listening, is there any chance of this
becomming "official"? seems like a mighty useful tool...
