OS 11.0 Thunderbird won’t start. I am dual booting with Win xp. So I keep Thunderbird’s Profile on a separate USB HHD.
Now every time I start it, It says that TB is running and to reboot the computer. To no avail. I check the profile and it has the .parentlock in it. I delete it and try again but TB puts it back in again.
How can I make it start?
Thanks,
Ron
