MANY thanks Bob, the file compiled first time AND I have a screen, albeit a very slow screen, but I believe that is a known issue that is being worked on. Was this file from RC-7, RC-Bugfix or RC-8?

Next I want to do a thorough comparison between your file and mine as it is bugging me as to what I did wrong.

Copious notes / spread sheets will be made to track this as we are heading down to Alabama for 3 months in the New Year, and I don't want to forget (again) how to make it all work!!

Again many thanks for the file and your help

Barry
