Hi! I might suspect the mouse driver. Not because it is MS--I like my Elite KB and mouse--but just on a hunch. Les Microsoft 3-Button Mouse with IntelliEye(TM): Vendor Name: Microsoft Speed: Up to 1.5 Mb/sec Product ID: 64 ($40) Bus Power (mA): 100 My Mac has begun to freeze intermittedly. It seems to occur in any application when I am simply moving the mouse. I have run Disk utilities several times yet the problem continues. Any insight to this problem would be greatly appreciated.
