computer or operator malfunction

[Ivor Hawkins]

I’m running the same Catalina OS Duncan, without problems...I can’t imagine what’s causing that particular problem, the only time I’ve seen something similar is when the battery level is low on a wireless keyboard, but that’s only when typing of course.

Time for the usual Mac trick I think, log on to the forum, pull the plug out of the socket, make a cup of tea and plug it back in again!
