Weird, yes. The value given by Windows for the wheel position is supposed
to be in multiples of 120. So I divide the raw value by 120 to give
the simple value. But of course, I used an integer to hold the result.

I've changed this now from 
   lWheelPosn /= 120 
to
   lWheelPosn = floor(lWheelPosn / 120)

Hope this still gives an accurate reading
