Actually, I first had to eliminate a non-powered 4-port USB hub from the mix when it seemed to be causing some instant-off issues. Nothing like getting near the end of a rather large document and having the system just "click" and it's off... Can you say "ARGH!" So now, just the mouse --> keyboard --> USB port, nothing else attached. Still digging, A.J.
