Why is my Thunderbird not responding? When trying to move or delete email.

more options

I have already tried the deleting trash folders and restarting and that does not help. When I try to delete messages or move them, the first two or three will go and then the program becomes unresponsive and I have to wait several minutes or restart it. This happens on several different computers that I have, all with Windows 10. Some have IMAP and some are set up as POP. It does it on all of them.

I have the same problem. I use AVG as my anti-virus program. This all started a few revisions ago. Never happened before that.
