WHY INDEED! I wanted to copy that thread for reference purposes but had not gotten around to it yet. A full explanation from our moderator or Nigel is in order. You put a lot of work into answering our questions, Alec, and that is one of the primary purposes of this forum - the free exchange of information. Your work has been negated and I have been denied a chance to save a printed record of that technical discussion. Lets have some answers now! And furthermore, reinstate the thread if it is still in an archive file!
