Faulty Mighty Mouse

I have frequently met people who tell me that their Mighty Mouse is faulty and that they want to bring it over for a technician to check as they suspect a hardware problem.

Usually the problem is linked to the scroll ball, which will more often than not only work in one direction.

The cause of the problem is not hardware, but simply dirt from your hand which has become entrapped in the scroll ball housing.

All you need to do to overcome this is to get a lint-free cloth, put a few drops of surgical spirit onto it and rub the scroll ball gently for a couple of minutes. Holding the mouse upside-down during the procedure helps to free the dirt more efficiently.
