Thank you for your prompt reply Dominik, I have asked everyone in the discussion on Notebook review to gather the information required and either post it there so I can reply or post it here in the list if it is from someone in the CC list.
Also thank you for replying to us all and not just on-list, none of us are subscribed to teh list so if a reply is only on-list none of us will receive it. Cheers. Michael.
