Since Russian OFFICIAL DELL support refused my request (although my laptop is on warranty), I've decided to try to find help here.
I've set middle click (wheel push) on a "three finger touch" touchpad gesture using windows 10 settings but each time I use that gesture, touchpad immediately stops working (algthough middle click was accoplished - I've tried to open a new tab in a browser and the tab has opened). Only reboot helps to get touchpad working again. Does anybody know how to solve that problem?
The problem occures on a Dell Inspiron 7567 laptop.
Hope someone knows how to solve that.
