Here's the problem... I can be working away on my G5, running 10.3.3, and when I mouse over the dock to switch apps I get the spinning beachball of death and my dock won't work. I can't get menus to work from the menu bar unless I hold the mouse over them for like 5 mins. And then I'm lucky if they work. I can switch between applications if I choose them manually through finder windows but its slow. The only way I found to correct the spinning beachball of death is to hard restart the machine by holding in the power button untill it shuts down. Then I can continue working once I start up again. It appears at any given time. Sometimes more than once a day. I've tried running Norton, resetting PR, verifying permissions and fixing any problems either may find but the spinning beachball of death keeps returning. HELP!!!
