An e-mail body displayed does not match subject header. This is rare, 1-2x per month and for a single e-mail. The subject line above and below (even though rest of header matches body) is for a deleted e-mail. I've seen this most often with e-mails left in Inbox for several days. Windows 11 & TB 115.4.2 (but has existed in earlier versions as well) Update: This may have to do with TB crashing in Calendar and the only way to terminate it was to use the task manager to terminate the process. These crashes are cause by changing a calendar entry in Google on phone and on TB before TB syncs w/google (which seems to only happen when TB starts).
