Thanks John, very kind of you. But I have to admit that I'm getting rusty now as I'm not using the knowledge I accumulated from messing around for literally hundreds of hours with cfg and air files. I make notes at the time but at the end when you've done what you want, they tend to get lost as they're so disorganised. So if you don't keep fresh by doing similar projects you begin to forget things.
Such is life I guess....
