I have a very weird problem and wonder if anyone else has experienced it. I have several users on my machine- QS/867 10.1.4- and only one of them has a problem after computer wake up- the mouse/keyboard does not work anymore and the red laser light is gone. The only think I can do at this point is to restart the computer. The mouse/keyboard is connected directly to the tower, not to any other USB device.
No other user experiences this problem. There is nothing in the start-up window pane (not even the iTunes helper app).
Thanks.
