Tape the paper to a hard surface at two opposite corners. Grip the Mighty Mouse upside down with the scroll ball touching the paper.
Push and pull the Mighty Mouse forward and backwards, the left to right a few times.
You should now plug your Mighty Mouse in to you Mac and test the scrolling functionality. All should be well. If not, proceed to the next step.
If scrolling is still not restored, spray a LITTLE degreaser into the paper. Wait for it to soak in for a few moments.
Again, grip the Mighty Mouse as before.
Repeat the same forward and back, left to right action as before.
Now test the scroll functions!
