Panther has been running pretty well on my original 500 Mhz TiBook except for one thing: hard crashes after the computer has gone to sleep or after sitting idle for some time. I haven't been able to link it to any one thing/app/network state, etc. I come back to the PB in one of two states: 1) Screen on, but frozen (can't move cursor, keyboard useless) w/fan on full force non-stop; NO ability to force quit or get anywhere; the only option is to hold down the power on and wait for the shut down, then re-boot. 2) Screen dark; HD spun down/inactive; won't wake from sleep (yes, plugged in); must use power down/reboot sequence above. Any suggestions? Many thanks, j mcd --- John McDaniel johnmcd at one.net ---
