Great... now I have a place to start, a methodology, and have a clearer concept of what to look for in the negatives. I will do some testing this morning.

Also, I must say that I sincerely appreciate how generous everyone is with their time and valuable information.... I know this is 'business as usual' at APUG, but the high quality of responses to all of my postings it is still amazing to me. Thanks again, Annie.
