Paul,

Huh! It was turned on, but I've no recollection of ever doing this. And, as
I wrote, it's never before been an issue. So I turned it off.

Could be. I opened LyX, looked in preferences (but not Display), exited,
then found Display and turned off instant preview. There were to *.tex files
using the CPUs after I exited the second time. Killed both processes.

If yesterday's files were in /tmp find should have found them. It didn't.

Anyway, however the instant preview became active it's now off. Must be
pandemic related, eh? :-)

Stay well,
