16..I also have a newer one but didn't seem to get good at it. I like how 16 just lays everything out for you in web search and I am doing a broad project of Irish people in a certain town...so I am interested in speed rather than depth.
Anyway, I have turned machine on and off several times, tried new default browser..it was working fine and then it stopped. I think I can find my installation disk but I am not sure. I will reboot tonight when I get off work. mg
