For some time I have been having trouble displaying previously downloaded and read messages, mainly in the inbox. After clicking in a message its subject and receiver is different or invisible. At the same time the message body itself is displayed in HTML format….And belongs to quite different mesage!!! If the message contains attachments, they are not visible. Mail server type: IMAP. Logging directly on amy mailbox from web browser the message looks correctly. Being logged into my inbox through a web browser and performing the operation of moving this message to another folder and then moving it to my inbox causes the message to display correctly in tunderbird. Screens attached

Sincerely
