DolbyMan, thanks for responding and for the kind offer.
As it happens, I think the problem just solved itself. Perhaps there is some kind of restriction on me because I’m a new user?
Anyway, I went back to my posts to find the offending one and… it was no longer showing. Very odd, as it was stubbornly refusing to go when I put the first post in this thread last night.
Oh and if you’re interested, here’s a link to the all-new thread that I was trying to edit. Please note this one is now “all good” [unless you spot any mistakes….]:-
