Folks, In last days I had my mouse "die" several times on 10.4.10 MBP, basic symptom is that once I leave computer standing for 1-2 hours and come back, system does not react to left mouse button! Right button works randomly but also not very reliable. This is 100% not problem with my mouse, I had both BT MM and Logitech USB Mice connected and they both exhibit same behavior. System itself is working, I can do some stuff using keyboard (Expose, switch windows, use shell). Unplugging does not help, the only way to solve this is reboot. What is this?
