If an IMAP server doesn't support user-defined keywords, we lose tags when you move/copy messages between imap folders. fix upcoming...

this fixes it if you open the destination folder with the same TB profile as when you move/copied the message...

fixed on trunk and branch

Still does not work for me with ThunderBird 2.0.0.0 against Fedora Core 6 imapd (uw-imap-2006g-2.fc6). It seems this imap server supports keywords/flags because after logging from another computer I am seeing all my flags on messages, so this information is not stored locally.

keywords are not flags - flags (like read, replied, marked/flagged) are supported by pretty much all servers. keywords are not supported by a fair number of servers.

Thanks for the explanation, but regardless what the imap server is supporting, TB has all the info about flags and tags (like Important, Work etc.= keywords ?) for the message in the source folder, even if it is an remote folder (and in my case I see all this information from all computers I am logging in my imap server). So I think there shouldn't be a problem to copy/move this information to the target remote folder with the copied/moved message. If it is another bug or if it is a planned, but not already implemented feature, sorry for my posts. I searched through bug database and this particluar bug seemed closest to what I was looking for.
