drunk mouse syndrome

( n.)

   (also mouse on drugs) A malady exhibited by the mouse pointing device
   of some computers. The typical symptom is for the mouse cursor on the
   screen  to  move in random directions and not in sync with the motion
   of the actual mouse. Can usually be corrected by unplugging the mouse
   and  plugging it back again. Another recommended fix for optical mice
   is to rotate your mouse pad 90 degrees.

   At  Xerox PARC in the 1970s, most people kept a can of copier cleaner
   (isopropyl  alcohol) at their desks. When the steel ball on the mouse
   had  picked  up enough {cruft} to be unreliable, the mouse was doused
   in  cleaner,  which  restored it for a while. However, this operation
   left  a  fine  residue that accelerated the accumulation of cruft, so
   the  dousings  became  more and more frequent. Finally, the mouse was
   declared  `alcoholic' and sent to the clinic to be dried out in a CFC
   ultrasonic bath.
