After a couple of reboots, the problem seems to have abated. I don’t know whether it was a bad install update or what, but so far, it’s better.
Thanks so much for your help.
You know, now I'm getting an error message when I try to print a web page using the printer icon on Firefox, "C:\Program Files (x86)\Adobe\Acrobat 2015\Diag.) Cannot open this file. Please check that the correct path and filename are given."
How do I fix this?
