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.
