I love those lightbulb moments. You wouldn't have got it without the patience you obviously have. Cheers
I had to do some work getting Mac to stand by a mounting block . His owner just mounts from the ground, but I am short, fat and old, so I need a mounting block. I got Mac so that all I had to do was lead him to it, me climb on and then circle my hand in the air and say, "over" and he woud sidle right on up for me. It always blows people away when I do it for them, but of course, Mac doesn't do it 100% of the time.
