Report "I want to reprogram the mouse button from the left back to the left front. The Kensington site says "Open the MouseWorks application", but I do not have a manual, and do not know how to open it. Could you kindly advise how I can do this please, also how I could obtain a copy of the manual. I would like to know what the ring around the ball does. I am a senior with arthritis, that's why I need the reprogram. Thank you for your help. Alva McNab"
