this started just yesterday. when i launch Mail.app, it comes up, grabs a few emails, then hangs before it can completely launch. right now, it's hung on "Erasing deleted mail older than 7 days". before, it hung up on trying to count unread messages in the Sent folder. it hangs the entire machine, Force Quit doesn't even work. i have to disconnect the battery (yikes) and restart. i've tried, to no avail: - resetting permissions - running Disk Warrior so i deleted the preferences. when i launch it now, i get a bunch of "things are locked" messages: anyone know how to unlock these mailboxes? i'm not at all unafraid of the command line.
