Hi Brian,
Perhaps I can help explain.
With a normal mouse Right clicking on a mouse you just hit the button. The surface 1 and any Wacom penabled tablet pens also work like this.
BUT with a Surface 4 (and 3) right clicking on a (surface) pen you have to press AND hold AND THEN WHILE HOLDING, tap the screen. It seems like a little thing for people who don't really need pens, but for artists and professionals its a big difference.
Basically hover-click has been disabled.
The n-trig hardware fully recognizes the hover-click state and even gives a circle around your cursor to let you know its hearing the hover-click action. But it will not do anything until you tap the screen.
Back in the day you only had to click the button on the pen within a cm - inch of the screen, but one day Microsoft thought it would be better to disable hoverclick, much to the frustration of anyone who actually USES pens, because this is much harder on
the wrists and no more accurate.
this holding the button, in tandem with how hard you have to press on the sp4 pen is what
gave me tendonitis
It should be made a checkbox preference in the pen settings.
Thanks for your help.
