Actually, George did acknowledge the error, and said that he doesn't consider it enough of a priority to correct it right away. My guess is he simply forgot about it over time. I don't have time to go through the archives to find that old discussion, so someone else will have to do that.

Unfortunately, I still am not in a position to spend time to read and consider entire threads, and then research and compose (in my efforts anyway) usefull input. I enjoy reading when I can, and have many fond memories of stimulating discussions on the e-porch.
