Thanks PP and complements of the season also to you.

I am just returning the help given to me over the years.
You may note that I tend to reply to unanswered new posts as they seem to be from people in my same time zone (At least being awake at the computer at the same time!), and I keep away from stuff associated with animation and Poser. 

I may not have the right answers but I may steer ideas solving in a new direction!

All the best

Brian
