Changes

If you close, shut down or exit Thunderbird (or Thunderbird stops on its own) and you see the Thunderbird '''process''' is running in MS-Windows task manager (taskmgr) or linux process status (ps), then you have a shutdown hang. Or perhaps you encountered a message that "Thunderbird is already running". The ("already running" message can be a symptom that is not related unrelated to hangs, so it is essential that you check taskgmgr or ps to find thunderbird there; if you don't see thunderbird listed, then you do not have a hang.)

There are several '''What to do:''' 1. Go through the full [[#Symptoms|symptoms]] list below. 2. If you find one of the [[#Reported Bugs|Reported Bugs]]is an exact match then cc yourself on the bug, but please only comment in a bugif you have new data to add. 3. If no bugs match, or then report a new one, and provide detailed symptom information which you can obtain from the [[#Symptoms|Symptoms]] list below. In other wordssummary, just reporting or commenting that you see a hang is not useful - please support your report with symptom data.
