Thank you - I'm kind of embarrassed. Before I got my Powerbook replaced I hadn't used Mac in a while. Since I have a Macbook Pro, I'm using it more and had a huge brain fart. Apple makes things easier - natural - and Windows doesn't do as good a job in this department. I was looking and googling how to do this and couldn't find it.
