Ya, I have a 12 inch 1.5ghz Powerbook that does the same thing. About, oh two weeks ago I think, someone stated that it was a known bug/problem. I found a report on it on apple.com (before the last OS update). It seems as if it is low on the list of things to fix. I can't burn CDs or DVDs, also DVD Player will crash the laptop, forcing me to use VLC to watch movies. -Scott On Jun 11, 2008, at 10:16 AM, Dr. Trevor J.
