    I have the ***-35PU and just finished fixing it. I found that lint/dust had gathered at the scroll wheels.
    Here is how I fixed the problem. Carefully remove the 2 rear white glides at the rear of the mouse - the side away from the wire. Use tweezers and gently pry them out to expose the retaining screws that hold the top of the mouse to its base. After removing the screws, gently lift this rear section away from the base and slide it slightly rearward (away from the attached wire). Note the 2 small slots at the front of the base which receive the 2 small protrusions from the case top. Sliding the small protrusions into the slots and reseating the rear of the case is an important alignment before replacing the mounting screws during re-assembly.
    Now that the mouse has been opened, use the tweezers to remove the accumulated dust/lint by the axles of the scrolling wheels. You will notice that the wheels have optical semi-conductor sender/receivers beside them. The sender projects light through the spokes on the wheels to the receiver. The dust/lint has interfered with the light path causing the unreliable scrolling performance.
    Be sure not to touch, with your fingers, the adhesive side of the 2 white glides that were first removed to expose the screws. The oil on your fingers will reduce its adhesion to the base when replaced.
    This opening and cleaning procedure also fixes problems with the left and right mouse button reliability problems due to mis-alignment of the top and base. My mouse also had this problem too. It works great now.

Check the mouse settings in the control panel, and be sure it's set to 4-5 lines, and not whole screen.

My scroll wheel skips, jumps, scrolls backward or on its own. Can I fix it?

Take the roller ball out of the bottom of your mouse if it's the older style and clean the dirt and dust of the roller wheels with a q tip and alcohol. If it is an optical mouse try putting a piece of white paper under it when you use it this may help. If not it is time for a new one.

The mouse wheel causes the screen to jump around sporadically and cannot be used with any degree of effectiveness. Is there a setting somewhere that would help me?

If you try all of the above and the problem is still there, especially if nothing about the problem changes and it does exactly the same thing it was doing, you may have to remove the batteries from the mouse, locate the screws that are holding it together ( a couple of them may be hid under the rubber feet) and remove the top cover of the mouse. Look around the scroll wheel and see if there is a lot of fuzz or lint around it. Remove the offending fuzz with a pair of tweezers and put the mouse back together. Now it will (probably) work like new!

Screen jumps up / down, scroll wheel not working

My guess is that the scroll-wheel is being pushed down, even when you don't think that you are touching it. It might be "locking" in the "down" position, thus causing it _not_ to work when you do try to scroll.
