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,
the AES will attempt to redraw the specified desktop, but the resource for 
that desktop will have been released at the time that the program terminated.
It is my understanding, although I haven't tried it, that wind_set(WF_NEWDESK)
with an address of 0 will reset the desktop.
