<p>Greetings to everyone!</p><p>I would like to post a bug in version 4.63 of Pegasus Mail.</p><p>I faced the bug while working with IMAP folders (categories in terminology of GMail web interface) of my GMail accounts.</p><p>Pegasus Mail shows correct amount of messages inside IMAP folders in time while it gets content of IMAP account from the server first time or when I reset a folder cache manually.</p><p>But after clicking on folder it reduces amount of messages in the selected folder (some of messages become missed) and shows incomplete list of messages.</p><p>In system messages window of Pegasus Mail I can see the following:</p><p>Mon, 17:23:19    IMAP: UID 1 not found in header cache Mon, 17:23:19    IMAP: UID 2 not found in header cache Mon, 17:23:19    IMAP: UID 9 not found in header cache Mon, 17:23:19    IMAP: UID 10 not found in header cache </p><p>All other email clients I have used for tests (Mozilla Thunderbird, Claws Mail, Novell Evolution, Balsa, Emacs Gnus, Zimbra, theBat) are showing correct content of these IMAP folders. </p>
