I've recently upgraded my Samsung ATIV smart PC 700T to windows 10.
I've been using the pen button as a right click (hold pen button and touch to right click) and since the upgrade this hasn't been working.
I've checked the pen on other devices and tried other pens on this device and still nothing.
Setting long-click with pen to work as right click also doesn't work (although it does with normal touch). Also, holding down the pen button used to display a circle around the pen pointer before the upgrade (win8), and now that's gone too.
So it looks like windows isn't recognizing the pen button at all, and also no other right-click options work.
Would love some help, and I'm not sure Samsung is supporting Win10 just yet.
