Hey Dennis: I have quietly been observing the discussion surrounding Walter Huegel's arguments. I suggest that it is time to stop piling on Walter. He makes some excellent arguments and the responses to them have become increasingly strident. Let's try some of your own philosophy here, i.e., live and let live. I get the uncomfortable feeling that we might be driving Walter off the network (it has happened before). The Parkinson's predator rides all of our shoulders, gnawing, slashing, and eating at us. Let's turn our attention back to it and away from attacking one another. Back off, Dennis. Prof. Jim Bill
