Yeh, I don't doubt there is a problem. I guess I need to take a closer look 
and see why it works. But finding the time to work on something that actually 
already works is difficult...(got plenty of stuff that doesn't work to keep 
me busy).

You're welcome. But all I did was put the framework in place so that you and 
Richard and others can make it work correctly ;)
