I had this happen a few more times under 10.5 but it seems OK under 10.4 so I am wondering now if it is a hardware or software issue. I tried 10.5 fresh installs on 2 different drives and a fresh install of 10.4 on the original drive now in the machine so I do not think it is my install procedure and I did full updates on each as soon as install was done. I took a few pics and will post one to see if this looks like graphics/logic board issues or not. These were taken under 10.5, when this happened machine totally froze except cursor for the mouse was moving and visible. The only other action was spinning beach ball, had to hold the power button to shut it down and restart it. I had 3 apps open, Safari, Firefox and Mail so I was not exactly stressing the machine. This happens on BOTH the internal display as well as the external, the first pic is the external display, the rest the internal display.
