Hi again Jane , If I were you, I would at least update to 10.2.8 . I don't know how old your imac is but I found re-starting helped my old i/book (three years old) when I was using Jaguar, especially after Classic had been used . As far as Panther is concerned I got it with my new imac but I am not that impressed with it. The so called improvements are cosmetic with a few little add ons such as Exposé which is good but you can live without it, otherwise everything is the same and in some instances not as good . I have had several little annoyances with Panther which I can't rectify. Cheers, John.
