I have a MacPro 3,1 - 8800 card went bad and upgraded to 5770 and Snow Leopard. Running the LaCie monitors... occasionally after the Mac goes to sleep, when I wake it up the cursor goes spastic on one of the monitors. Works fine on 2 monitors, but when I drag it to the third, it starts bouncing around the screen on it's own... have to restart Mac to make the problem go away... any ideas on what's causing this?
