Sorry I have not contributed to this thread to date but I have been tied up with work. Viewer 2 is not really suitable for use with Windows XP and XP uses would be better suited using Viewer 4 which is available separately, Viewer 3 has been discontinued as a separate release. See the bottom of my page http://freepages.genealogy.rootsweb.com/~framland/framland/1881.htm for options. As to the speed concerns, there will be very little difference in loading times with virtually any modern Pentium (or equivalent) based machines the speed, size and fragmentation of the hard drive would have more effect on the loading times.
