Hi Edward
Thanks very much - you have beaten me to the steps I was going to take
following Thomas' reply.
I only have small time windows to investigate and experiment with Leo, my
first post was to check whether others have the same experience.
I came on this morning (UK time) to say "Thanks Thomas, I am guessing that
there will a setting governing this behaviour, I will follow up".
PS: your comment about only c.X methods affecting the gui makes sense, but
I had not fully appreciated it, thanks
Regards
Jon N
