We are running into an intermittent problem with Finder copying from an AFP share where I work, occasionally Finder will say that the user doesn't have sufficient privileges for the file, even though a command line cp works just fine. I have no idea why Finder is choking on it and it doesn't give me any sort of console logs to tell me either. Is it remotely possible to run Finder in any sort of verbose mode where it will actually give me more info about what is going on?
