Thank to all of you who offered suggestions on correctly configuring
this system (problem description at the bottom of this message). I was
overwhelmed by the response to my posting. Below is on of the most
consise explainations of my problem and it's solution. Many others
offered the same or similar advise. Again, I thank you all.
