It really does not do any good explaining these esoteric issues in this board. Someone should send these commnent to the appropriate people. (Fred?). It is amazing how many simple things one may overlook no matter how good that person might be in what he/she does. We all fall in an intellectual rut and it becomes very difficult to get out unless someone points out the obvious to us. It has happened to me many times and I think am pretty good in what I do. Please try it and I am sure you will not regret it.
