Now I had a lot of messages in some of the accounts which I have deleted and am deleting. Any ideas?

I will click on Thunderbird and then nothing happens. I try click again and it tells it's already open and it may be running but it's not there on the screen.

Task manager in Windows 10 shows it though.

So I am at the point of just getting rid of Thunderbird altogether.
