Judy, As regards question #1, I have no experience to help there. As regards question #2, I worked with Advanced Argus for Windows (1C Release) with the PHIDO project in Philadelphia (Pennsylvania Historical Society, Atwater Kent Museum, Civil War Library and Museum, and Civic Center Museum), and have seen it at the Mint Museum. I currently work with the 1D Release of Intermediate Argus for Windows at the Brandywine River Museum in Chadds Ford, PA, and love it a lot. It is a vast improvement over version 1C. I know Janice Dockerty, late of the Historical Society of Delaware thought the 1D Release was a great improvement over 1C. I've not heard from anyone else lately. I'd love to hear the results of your query off list, if not here. As regards questions #3 and #4, I have no information. If you decide on Questor, please let me know what you think of it. If I can help in any way, I'd be more than happy to. Ruth Bryant Power Registration Assistant Brandywine River Museum
