huh. I haven't been syncing my ipod lately, but i did get a spurious disk full note just before mail.app went on to hose all of my prefs, drop some mail and refuse to recognise an mbox or three. rebooting and rebuilding my prefs got it going again, more or less, but i'm planning on scrubbing everything and starting over, in the naive hope that 10.2.3 will be better.
