I posted the message below last week, but I've had no response.

Is this the wrong list? Did I do something wrong in my posting?

I would like fix this problem, and I have more information now, but I
don't want to clutter this list if it's the wrong place.

Guidance as to what I should do gratefully received: thanks.
