Hmm, 8.1 doesn’t see it as an advanced touchpad then.
With Windows 10 none of the 3-finger gestures work. I was wondering if it was a driver issue but it needs to be an advanced touchpad for them to work as far as I know.
Does your device manager show it as a generic HID-Mouse or something else?
The gestures are hardware made in the dock – the right swipe send to the OS the Win+C combination, like you press on keyboard.
That’s why they don’t work on Win10 – there are other keyboard shortcut.
