Mouse

Every time I sit down to use Dad's computer, I immediately notice a problem.  I am moving the mouse, and it is having minimal effect on the pointer on the screen.

I open the mouse and find all sorts of gunk in there that I clean out.  The mouse is now working properly.  I am left pondering how Dad was ever able to use the mouse in the previous condition.

On my last visit, even after cleaning all the gunk out the mouse would not move the cursor in the down-right direction.  The only way to accomplish this is to move way right, then way down, then back up and left as needed.  I suggested to Dad that he fork over the $10 for a new mouse.  On my next visit, I will not be surprised to see the old mouse still there.
