Hello Bruce

Thank you for your valued responses to me - IMHO you have a wealth of knowledge (which I'm glad you are eager to share!)

I trust I am now posting as you have suggested.

Further query though. On the MS Communities web site, I can(and do) ask to be notified if there is a response.

I haven't found the same facility here, though (although I understand about the specs. and red text).

Is there an alert facility?

David B.
