After upgrading to OS 4.2, e-mail downloading (IMAP account) has changed. It only downloads about 7-8 e-mails and indicates there are 13,000+ more to download. Actually, there are only another 30 or so still on server. Pressing the download link only downloads a single day's e-mails (1-3) and the number still to download remains unchanged. Closing the e- mail program and reopening it simply repeats the problem described. Help!
