I applied the latest Windows 10 update to my Dell laptop, three or four days ago. Since then when I open Thunderbird, it comes alive fetches mail, tells me I have new messages then freezes. I can't interact with it in anyway. When I check running processes in the Task Manager, Windows sees that is open but doesn't think it is non-responsive, it just lists it as not using any processing power. I am 95% sure my T-bird was up to date before all this. It usually is. I have not installed or changed anything else. I have the pgp plug-in and I believe I have a conversations plug-in installed. Any help is greatly appreciated. I have a lot of mail accounts and really do not want to have to reinstall. Thank you.
