Is Select All not working?

[Pete]

Curiouser and curiouser... It's working again now, without any changes being made at my end! Yes, the code lights up now. I'm using Win10 and Chrome. I think it may be related to my virus scanner but don't know.
Anyway, thanks  both for responding. Maybe the "bug" got scared off when two "heavyweights" appeared!

"got scared off when two "heavyweights" appeared!"

Are you saying Steve tipped the scale?
