Flattop. You are quite right about my being fed up with the number of threads that are all about the same subject. (a very human emotion) I have been dragged into this unwillingly and withdraw. Your remarks have become personally directed insults. My comments are not directed at any individual in that manner. I dont object to differences of opinion, but insults are just that, and serve small purpose. I dont care to enter into that kind of childish exchange with anyone. What could be a difference of opinion, calls for private exchange not public. Yours, Aye. Dave
