Thanks for all the info and links to this older thread Azizi. The next person will have a lot more info thanks to your posts. Much appreciated. Too often after a thread answers enough to satisfy the poster (in this case Murray in Oz) it gets dropped. Glad to see your additions here.

And I'm sure my old friend Murray would thank you too but sadly he left us a few years ago to play air harp with the angels. He was a great 'Catter!
