Hi, nals.

Don't have any idea what might have made your iTunes library disappear, other than your iTunes update. When you look at the library in Finder, are the files still there?

Regarding mail, assuming you're using Smart Update and "Backup - all files", we do copy the files, and the read status is either with the files (pop) or with the server (imap); I can't see why it would be any different on the copy unless it's IMAP and hasn't yet been synced with the server. Could that explain?
