I've tried the demo program and this is working correctly.
But so far I've not been able to see a difference between this code
and my own code. Furthermore,s when using the old library also my code 
works,
so this is still a bit of a mystery to me. I'll dive into the code some 
more this weekend.

Hmm,  should have become a member of the list years ago ...
I wrote 2 programs in 1998 - 2002 or somewhere about that time and
haven't changed any of the code in a long time.

Well, I almost don't dare to ask, but would you please?

I'll try to isolate some of the code and get back to you.
Thanks for your comments so far.
