Two reasons Graham  -   One is that I always like to know how things work since that gives me a better understanding when thing (inevitably) go wrong,  but the more important reason is that I can't get the Wizards to work 

I have found the Wizards List as you point out and can select [Circular Pocket] or any of them for that matter but whatever I do after changing the parameters and clicking on [Post Code] when I click on [EXIT] nothing happens and I have to close Mach3 and re-start it      so obviously there is no code in the window.
