I'm not sure how it happened but I was browsing around tonight when my Dock started crashing fairly frequently. Then, I noticed that my iCal Events widget wasn't showing any calendar data. Upon opening iCal...all calendars..gone. Checked for them using Spotlight and they're deleted, not moved, but deleted. Also, my Address Book data has reverted back to something like 2002. I'm missing over 2/3 of my contacts.
Lastly and maybe most worrisome, for a little while there, I was getting a periodic Finder error saying it couldn't find the server I was trying to connect to but I never asked it to connect to any server. This error always occurred twice in a row separated by long pauses between pairs of warnings.
After restarting, Adium is now missing all installed skins and preferences. Anybody know what's going on?
