Hi All,
TL/DR: The bug is still there after all.
Unfortunately I was wrong. After using this gray mouse for a day, I experienced the bug a few times. It's still there.
I've now owned three Arc Touch, Surface Edition mice. Scrolling stops working on all of them. It's hard to believe that there could be such a widespread defect that could go on for five years across multiple iterations of the mouse.
It's puzzling, because I have a Bluetooth Logitech MX Master mouse that works perfectly. There must be something unique to the Arc Touch mouse that causes scrolling to stop working. The frequency between occurrences of the bug seems to vary greatly, which suggests a subtle problem, be it mechanical, electromagnetic, firmware-related, or driver-related.
I've only ever used this mouse on Surfi, so I don't know what would happen on a non-Surface device. It would be very interesting to see if a drop in scrolling would occur when using it on a Linux machine (if that's even possible).
The Microsoft Store guys are clueless. Every once in a while I encounter one who believes that since he personally hasn't experienced it or heard of it, it the bug must not exist.
How does Microsoft get away with this?
Steve
