Possible Thunderbird glitch that MAY affect users.
Just updated Thunderbird to 38.3, restarted and it was basically unusable, no emails visible etc.
The fix.
Clear the browser cache Menu Bar\Tools\Clear recent history and the Windows Temp directory.
Shutdown any anti-virus software you are running. (optional, I never)
Download a new copy of the full installer from http://www.mozillamessaging.com/en-US/thunderbird/
Delete the directory C:\Program Files (x86)\Mozilla Thunderbird
Run the installer.
Restart the anti-virus program. (if needed)
