Thunderbird running but not responding... How do I stop it?
I have downloaded and installed Mozilla Thunderbird, since all my previous archived e-mails from my Windows install are in Tbird format.
After a random number of uses, I get the error message "Thunderbird is already running, but is not responding. To open a new window, you must first close the existing Thunderbird process, or restart your system."
Well, despite restarting my system multiple times, I still get the message. I looked up the manager with all the running systems, and Thunderbird isn't one of them.
The only way I can get around it, is to delete all the Thunderbird files, reboot the system, and reinstall Thunderbird. Very inconvenient.
Does anyone know what's happening here? or how to stop it?
