Solved - need to install eTouch driver (is not installed automatically)
Hello, After W10 reinstallation WX2VW passive stylus does not work at all.  Funny thing is that touch screen is fully working but not with pen, only with finger. I tried DELL driver installer, all updates from microsoft are installed.  In device manager, everything seems to be fine.  Pen alone is functional with mobile phone screen.  Any idea? Is there some hidden driver?  Thanks a lot David
