OCCASIONALLY CLEAN YOUR TOUCHPAD!
Its easy.....moisture and dust can sometimes make your touchpad not work properly so every once and a while wipe off the surface with a soft cloth and some alcohol (or similar solution) and re-plug it in.
Most problems with the touchpad can be solved by simply re-plugging in the touchpad.
You could also try cleaning the surface with alcohol or like solution, or making sure your plugged directly into a usb port on the computer and not a hub or usb splitter. Other possibilities try plugging it into a different USB port on your computer. Try the touchpad on another computer to make sure it is not a computer issue and also restarting the computer.
