I am having a problem with my Powerbook, OS 10.4. That is, everything works except for the Finder and the desktop icons, folders don't appear. This seems very odd as everything else seems fine--I'm using the internet right now--and all my files are intact, but the finder just doesn't come up nor do the desktop items. Does anyone have any experience? I went to the Apple Store and their so-called Genius Bar, but they were entirely incompetent as expected.
