Hi. I'm sending this on behalf of someone. She is running the latest Thunderbird for Windows [I checked] on Windows 11. All emails show up correctly when she sees the Emails in her inbox. But when she opens up some messages [no commonality between them], she gets the gibberish as in the attachment. Odd that every message with the issue has the same file name mentioned [IMG_5409.JPG]. If she gets an Email she is fine. She gets another Email and she gets the attached message. Later she could get another Email from the individual and she's fine again. Thoughts? Ed
