Thank you in advance for any thoughts you might have. Thunderbird was running fine until a few days ago. Then it suddenly started opening Inbox messages as drafts even when moving the previous message to Mail Read. Could not locate the problem. Discovered I was running a Version of Thunderbird in the high 90s. Upgraded to 115.31 (64 bit) on Windows 10 latest update. Same problem. I have tried every troubleshooting that I know (been using Thunderbird for about 18 years) on both versions. I can't find or think of any reason for this to start suddenly or persist after upgrade to newest version. I have a screenshot in both JPG and PDF if that helps. Searched support without finding this issue. Much appreciate any ideas.
