Reproducible: Sometimes Steps to Reproduce: 1. TB retrives message headers from the server. 2. I select one of new messages. TB downloads its body, displays it correctly and marks as read. 3. I work with other messages. 4. I return to previously read message. 5. TB still displays the previous message. It does not display contents of the message displayed in point 2. Two workarounds: 1. Select another message and select again the one that causes problems. This solution doesn't work in all cases. 2. Move message to another IMAP folder. Then when you select it TB will download it again from the server and display correctly.
I'm seeing this too. This might be a dup.
