[imp] Emails that are read are still being marked unseen

[Elliot Anders]

I recently (this morning) upgraded our system to horde webmail 1.1.1  
which uses imp 4.2 and we seem to be hit with this bug:
http://www.mail-archive.com/imp@lists.horde.org/msg01580.html
which in the list archives appears to have been fixed in 4.2.  Is  
anyone else seeing this problem?
Our imap server is running dovecot (1.0.beta3) and our previous  
version of imp didn't have this issue (4.1.5).  Is there a patch  
available or a setting I might be missing?
Thanks,
-Elliot
