Hello, The problem...without apparent warning, the system freezes up. I lose the mouse & keyboard completely. If I unplug them an replug them there is no change. The cursor vanishes from the screen. If there is an application in the background (ie: iTunes) it will continue to operate(?cached songs?), but I am unable to bring it to the foreground, also the DVD player frequently freezes the entire machine, requiring me to push the reset button on the fron of the tower. The machine...G4 Sawtooth, 512MB RAM (2X256MB), 40 IDE HD, DVD-RAM The system...a clean install of OSX 10.2 onto a freshly formatted drive. email me directly if you would like more info, as I am on digest mode for the list. tia Ed C __________________________________ Do you Yahoo!?
