You,Sir, are "The Man"! I followed the instructions and - viola - Joy in Mudville. Thank you, keep up the great work. Even the "Apple" people don't seem to know this. I was on the phone with them, passed from one to another, for over an hour. While waiting I stumbled on your advise and I was made free! If they ask you, charge them a mint for the information.
