since updating to 10.8.2...and since, twice, logging in to icloud on my mac...i've lost my signatures in apple Mail. the list is still there, but there is no information (in my case, 5 signatures with small images). so seems to happen after logging into iCloud. i can replace the signatures folder in my user library, and when i reopen mail...am good. but have done this twice in 2 days (am keeping a copy of 'signatures' on my mac for the next time). anyone else seeing this?
