This is a message from a friend of mine. I have seen this problem twice before. Once on ain ibook 500(mac os 10.1.5) with 256 MB Ram. And a powerbook 667(mac os 10.1.4) with 512 MB Ram. The only thing i was able to do with the other ones was wipe them and reinstall. once is a fluke, twice is odd, three times is a bug. I have sent an email out to apple and currently waiting for a reply. Has anyone else seen this problem and had any luck with it.
