I wonder > if it is driver related or really hardware related... That's normal. The hardware generates 80 packets/second and it keeps generating packets 1 second after you stop using the touchpad. Each packet is 6 bytes and the i8042 controller generates one interrupt/byte. 500 interrupts/s shouldn't be any problem to handle though. -- Peter Osterlund - petero2@telia.com http://w1.894.telia.com/~u89404340
