Thanks again, everyone, for your help. I feel a lot more confidant in using my Mac - I'm going to copy my Runtime from PC to an external disk drive (needs a new backup anyhow), then copy the external drive's data to the Mac. I really appreciate the help and support, thank you all for helping me with this. Thia Mac doesn't like dittoGUI, I think Snow Leopard is being persnickitty. :/ Off now to copy the monstrosity that is my Runtime (somehow I have a TON more stuff than when I started out- who knew I had 3 gigs of stuff in my Runtime! Whew!)

 Thanks again,
