thanks for the reply, John. I don't have a .Mac membership so don't have .Backup, although I tried the 60 day trial some time ago. Maybe there's something left over from that. I can't remember specifically what I was doing when the error happened, but it may have been that I was just checking mail. I also ran the P2P program "Acquisition". Don't know if that would do it or not. I don't know if this is related or not, but three or four times a day, I get a loud beep from the computer. I thought it was signalling that I had mail, but it isn't that because I turned the new mail sound off. I have a Mac Mini 512 Megs Ram, etc., just the usual configuration. I'm running OS 10.3.9.
