Running version 52.9.1 (from Ubuntu 18.04 repository) I have looked through the past several threads which have this issue and there do appear to be duplicate messages in all of the "stuck" cases on my system

In the attached image there are several threads that clicking on the '+' sign has absolutely no action. I cannot click the green circle to mark the messages as read either. This doesn't happen ALL the time, but seems to happen in particular when duplicate messages are delivered (in this case a yahoo! groups mailing list that occasionally sends duplicates) ProblemType: Bug DistroRelease: Ubuntu 10.04 Package: thunderbird 3.0.4+nobinonly-0ubuntu4 ProcVersionSignature: Ubuntu 2.6.32-22.33-generic 2.6.32.11+drm33.2 Uname: Linux 2.6.32-22-generic x86_64 NonfreeKernelModules: fglrx Architecture: amd64 Date: Thu May 20 15:22:39 2010 ProcEnviron: PATH=(custom, user) LANG=en_CA.utf8 SHELL=/bin/bash SourcePackage: thunderbird To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/583577/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
