I have about 5 Dell Precision Laptops that are all experiencing the same problem. The action that occurs when you press in the mouse wheel, the two arrows that allow you to use the movement of the mouse to scroll as apposed to the actual scroll wheel, is firing on it's own. I have tried re-installing drivers, I have tried disabling the at function so only the left and right mouse buttons work, but nothing has come up. Google searches have not proved fruitful either. They are all using docks, and it occurs if plugged in to the laptop or the dock. Thank you in advance for your assistance.
