OK, Leopards up and running. It can see all the shares on my Vista Ultimate boxes. It can read, write, boil in oil any of the Vista files. However, my Vista boxes went all snooty on me however and refused to recognize that the Mac exists. Entering the name or the IP address just returned an error. That was last night... And then - 12 hours later - NO changes, not even a reboot (honest) - the PowerBook suddenly appears in my Network folders. WTF? Time heals all things??
