Last month I upgraded my FC4 system to FC6. Everything went fine and has been working smoothly since then, until today. (Well, Evolution doesn't work very well with IMAP, but that's a different subject.) I have been doing a yum update each morning. This morning the only thing I updated was ginac. Now about every 10 minutes FC6 logs me out. It doesn't matter what I have running. I just tried logging in and not starting up anything, and I had the same problem. I am running Gnome. Earlier, after the 3rd time it happened, I got some kind of bonobo activation server error (3 or -3?), and the panel didn't open. So I rebooted and logged in and did nothing else, and I just got booted again. Any idea what's happening??? Dan
