When Thunderbird is (sometimes) very slow in deleting a mail and if one repeats delete n times, then Thunderbird deletes n + 1 mails when coming back to work.
Fix this bug. Surprisingly deleting multiple mails after a nice long (observed up to 50 s) sleep is imho not acceptable. To be clear: This post is not complaining about Thunderbird sometimes freezing when ordered to delete one mail. (That seems an old topic, closed but unsolved .)

complain about the hang, but your chasing your tail about the keyboard buffer getting emptied when the hang ends. No going to happen as the program in essence has no idea it was unconscious.
You might want to look at some of the tings here to try and work out why your copy hangs. https://wiki.mozilla.org/Thunderbird:Testing:Memory_Usage_Problems
Removing the windows indexing service from scanning the Thunderbird profile folder and preventing on access scanning by anti virus programs did wonders for my install.
Dear Matt,
thanks for your quick response. Of course, you are right: Instead of lamenting on the “awoken from dead” effect I should complain on the regular long freezing. But that and (re-) applying all sorts of googled tips I had given up since years.
From your link(s) I understood Thunderbird’s freezing is a Windows only and mostly indexing problem. As I had a handful of workstations doing indexing bring a medium sized AD domain to a halt I’m more than inclined to believe this.
I stopped all indexing (and will check this regularly as Win10 always knows better) and hope it helps.
Thanks again and best regards Albrecht
