My apologies, ladies and gents. I've just noticed that my new thread here has crossed in the post with a similar one from AprilHare here:

Perhaps one of our mods team could delete my thread and I'll post a comment in April's slightly earlier one instead because there is already reaction showing there.
Apologies and best wishes. Neil
