TIG,
I bow to your expertise, and will reinstall SU at some point. For now it is working well, no more SKB's, no problems.
I still do not understand why, of the many times and many computers I have installed SU on over the years, without using "run as administrator", it did not cause problems with these installs. I am not questioning the wisdom or correctness of your advice and recommendations, I'm certainly not qualified to do that. I just like to understand the whys and wherefores of things when I can. I guess I could just chalk it up to being lucky, but that's just not the way things go for me
Again, thanks
Steve
