Dodgepot and h1982,
Someone seems to have quickly updated the app AND installed it on my tablet while I was out walking the dog... Alternatively, I may have been blinkered and looked at the two letters in lower case with a full stop. I was sure that I looked at all options but that was in the early hours of this morning so I may have nodded off for a moment. (That explains why no-one else has complained about this.)
Thanks, both, for putting this numpty straight.
