The time counts up, but the CPU% doesn't. I'm reduced to "ps -p ; sleep 10 ; ps -p" and doing the subtraction in my head to try and back-of-the-envelope guess how much CPU e.g. Firefox is using. It's not a showstopper or anything, but it's _really_ annoying, and we're on our second -STABLE major version doing it. It's one of my least favorite bits to try and explain to somebody. -- Matthew Fuller (MF4839) | fullermd@over-yonder.net Systems/Network Administrator | http://www.over-yonder.net/~fullermd/ On the Internet, nobody can hear you scream.
