I think it was early last year I upgraded to 4.2 and I guess now I'm gonna have to pay up again. I had hoped I wouldn't so soon run into one of the few things they improve in upgrades. On my code, I really thought I was just doing something stupid -- again. I love those rare occasions when I did something almost normal. Thanks to all who helped me. Best regards. J. K.
