With an Inbox full message and couldn't download messages any more, I moved most messages to another folder under Archive but still get the same message. Reading from others' posts, I repaired Inbox but all messages there is gone and it keeps thinking forever. Tried compacting Inbox, it keeps thinking. Tried reboot and compacting (all) folders, it keeps thinking. Also deleted inbox.msf, which only one unused out of several email account's folder has, but no help. Sometimes when Inbox stops thinking, checking mail still gets Inbox full message. Wasted a whole morning already ... any idea please?
