I don't know of any O/S, from windows 98 to NT to any flavor of unix, that won't give almost exactly 50% cpu utilization. IMHO it is better than ponder=off as that is an unnatural mode for a program to run in. two machines would be even better, but one works fine just so you don't start turning this off, or that off, etc. > > >> >>Enrique >> >>>As anyone using F6 knows with ponder=on you get a question, >>>Permanent Brain on single processor?. >>> >>>Thanks
