ok this doesnt happen all the time but when it happens once it happens many times until i restart i have a microsoft intellipoint explorer opticla mouse sometimes if i dont touch the mouse for a long period of times and soemtimes even while i am moving it it is as if it gets disconnected, the mouse light goes offand acts as iff there is no mouse even plugged in i swapped usb ports with my keyboard to see if it was just the port but no it still does it even ion the other port it sometimes sjust acts like there isnt even a mouse connected so i have to unplug it and plug it back in and sometimes that doesnt help or soemtimes right after i get back up off the ground from plugging it in? i will start to move the mouse and the light will go off again very annoying i have the latest drivers for it too anybody have any ideas as to what is going on?
