Intermittent mouse problem fix (Score 1)

My best hack was closing the window curtains to get a mouse to work. It quit working one weekend and I bought another one for a few bucks. Next weekend the same problem came up. I thought about cleaning it, but remembered it was brand new. The old cheap mouse had a thin casing and a ball tracker moving wheels with spokes. It worked OK at night, but during the day the sun hit the side of the mouse and lit up the motion sensors, making it unresponsive. Can you imagine phoning a help desk complaining about a mouse problem and they tell you to close the drapes.
