No,..I wasn't trying to get you, Frank. I just had my head up my axx, for a few minutes. It hit me, when I was well on my way to Salt Lake yesterday,...and it was too late to correct it. The set I worked on, had 3 Tantalums in it. They can cause your problem. I just thought yours might have bee similar.
