Recently I have had problems with MW showing the same message detail more than once.
It happens intermittently. MW seems to see new messages on the server but adds frustratingly displays them as duplicates of previous messages (both the header and content).
I saw a post elsewhere in the forum suggesting that 'pipelining' should be disabled.
However I use IMAP and the option for 'pipelining' does not appear for IMAP accounts.
How can I resolve this issue?
