I followed the instructions in
http://insideoe.tomsterdam.com/tips/slownews.htm
and the problem is now completely solved.
So there's no reason to go to the trouble of changing newsreaders and
teaching myself how to use one or the other. There never was.
When it comes to understanding how the Internet works I am a novice.
On the few occasions I have asked for advice I have found THIS
newsgroup to be the most helpful. I have difficulty in understanding
the advice issued by the experts on the other newsgroup. It's too
technical. They talk down to me. And I am not a member of their
club.
Thank you all very much for your interest.
