ElderN: Thank you for the good response. I tried the first suggestion in your list, but not all the others.
I'm a little afraid of making things worse rather than better. I appreciated your comment to someone else about leaving automatic updates turned off as I've experienced problems with that too...having to restore to a previous time.
Yes, so far the list of questions from PA Bear has gone nowhere and taken a lot of time. He has now asked me not to respond to him anymore.
I'm teaching pretty much 24/7 (online as well as onsite) so I'll follow up on, I think it's Volume Z, and see if s/he has something to add.
Love your quote about teachers.
