Hi, I have a mx 3 master mouse (pc), it started playing up over the last week or so and has today gotten to the point that it is completely unusable. The mouse cursor tracks across the screen fine but one moment nothing other than the movement will work (scroll or any buttons won't work) or it won't work on a document you have open but you can click on the taskbar, then another time it will do the exact opposite. when on the web it is going back a page all by itself which is highly frustrating. I've tried updating the drivers (latest already on it), updated logi options+, tried to go to an old driver (wouldn't let me) and removed the device completely and reinstalled, also factory reset twice. i have also tried on a different computer and have the same issues. I am using the usb dongle rather than bluetooth which i have swapped into different ports and doesn't make a difference. Sometimes turning the device off and on again brings back some of the function but only for a short period of time.
