Sometimes, when I delete one email from the inbox, the inbox shows "no message found", even though there are still other emails in the inbox. The remaining emails are still in the inbox, they just don't show. If I right click on inbox in the left panel, and select "open in new tab", the remaining emails show in the new tab, just not in the main inbox. If I close out thunderbird and start it again, the emails show in the main inbox. The problem occurs occasionally, whether I select delete from the menu bar, hit the delete key, or right click on the entry and select the trash can icon. This problem started maybe 10 or more updates ago. For each new update I think "surely it will be fixed this time". I have included a partial screenshot of what it looks like after the problem occurs. This problem is different than any other questions I have found in the search. It purely a visual presentation error, not disastrous, just highly annoying. Any solutions will be greatly appreciated.
