Hello Maurice.

Yes, it explains a whole heap better what you have been on about ....

Thanks ...

I usually don't check them all, but I have yet to notice a dupe, that I cannot 
find in the echo base where it should be, will check all dupes, next time I 
get a batch, even if there a 300+ of them. :-((
