Hi Scott,
This thread is specifically for the Microsoft Arc Touch, Surface Edition mouse, not the Microsoft Arc Mouse or the Microsoft Arc Touch mouse. These are all different mice.
Your solution doesn't work for the mouse that we have, the Arc Touch, Surface Edition mouse. Based on multiple posts here, some of which link to YouTube videos or websites with photos, it seems that the Arc Touch, Surface Edition mouse has a hardware design and manufacturing flaw that cannot be corrected through software.
I intend to return mine--sadly, because I prefer its ergonomics and battery life to that of my Logitech t630 mouse. The Arc Touch, Surface Edition mouse isn't a usable product.
Best,
Steve
