I can't use Thunderbird any more. I open an email and I get 7 copies up across the top of the screen. Delete does not get rid of them, and I am up to over 50 at this point. Please contact me directly at [removed phone# from public support forum] when you have fixed this. For reasons I have just outlined, email is not a good way to communicate. I assume that everyone else is experiencing this disaster. Ernest Isaacs
