Done, sealed and in the post. Some satisfyingly weird setting - it's taken me till today to worry out a group of lights in the middle bottom area that drove me crazy (as I've told you all ad nauseam I'm honour bound not to seek any help or look up anything, but do it all in my own head - I only come onto this forum after I've completed it and sealed it in the envelope, to check what other people have found difficult).
Somewhat embarrassed to find that my Quixote alias is shared by a distinguished setter who got there first - I didn't know, honest! - probably should stay in more. Can't do much about it now. Change it to 'Hotie', maybe? (You know - the First Novel was originally entitled "The Adventures of Sancho Panza with his Donkey, 'Hotie'...." - one of the great literary misunderstandings of all time.
