Cannot continue deleting messages after first four or five
After opening Tbird inbox I commonly find many unwanted or uninteresting messages, and begin deleting them from the top. After four or five deletes, Tbird freezes, unresponsive to mouse or keyboard. I can wait it our (several minutes) or go to task manager, highlight the program, but not close it, and return to Tbird, and it resumes deleting unwanted messages, opening wanted ones, and so on. This occurs in Windows 10 professional, Tbird 38.70 and seems to reappear in this morning's update from 38.70.

What is your anti-virus software?
Currently using Vipre, but the problem was the same while I was using Norton
Try to start Windows in safe mode with networking enabled. - Win10 http://windows.microsoft.com/en-us/windows-10/change-startup-settings-in-windows-10#v1h=tab01
Still in Windows safe mode, start Thunderbird in safe mode. - https://support.mozilla.org/en-US/kb/safe-mode
Does the problem go away?
Problem goes away in safe mode but returns in normal operation
Windows safe mode disables anti-virus software, which is most likely the culprit.
Create an exception in your anti-virus software for the Thunderbird profile folder, so that the anti-virus real-time scanner will not scan it. http://kb.mozillazine.org/Profile_folder_-_Thunderbird
Don't let your anti-virus software scan incoming and outgoing messages.
Don't let your anti-virus software scan attachments.
Don't let your anti-virus software intercept your secure connection to the server.
Remove any add-ons your anti-virus software may have installed in Thunderbird.
