I am running 0.1-rc1.1 on apache2 with dovecot IMAP server. The browser I use is firefox 2.0.0.4.
When I log in to roundcube, a couple of folders flash say they have new messages in. About half a second later, these folders no longer show the new message indicator. When I go to the folders, there are no new messages in them. This also happens when I move a message to another folder - brief new indicators & then nothing...
The only way I've found to cure this behaviour is to delete all messages from a folder!
Also, folders that DO have new messages in (other than INBOX) don't show that they have new messages! But that's another bug...
See also http://trac.roundcube.net/trac.cgi/ticket/1484431 where I reported it as a bug on trac... any ideas?
