I think turning off the plugin may have made things worse. It appears to turn all inline attachments into orphans. You see " [ Attachment Invalid Or Does Not Exist ] " in the message, and the thumbnail of the attachment at the bottom, but when you click on the thumbnail, nothing happens. Your pic of Admiral Ackbar is an example of this. And I've looked back at some of my messages that had inline pictures, and they're now all like that - no way to get to the pictures anymore.
