I have an indigo ibook running 10.1.5 and I can see the damn linksys router, but I can't see the program on his computer, I can't even see his shared folder. I'm so sorry, I don't really know a thing about java, or Os 10.1.5. I'm still so used to OS 9. I have been looking for info all over the web, but most of the info is about the current mac os, and that's not going to help me. He's running some kind of windows environment, wish I could be more specific but I don't have his pc in front of me right now. Help -- help help!
