My stylus stopped working a little while ago and I've just bought a new battery for it. With the new battery, the stylus creates a dot on screen (and a circle if the right-click button is pressed), but it doesn't register taps. It's like it's constantly hovering just above the screen.

I'm using Win 8.1. Tried the 'calibrate the screen for pen and touch', but this doesn't work because it wo't register taps! Very annoying.

Does anyone know what drivers I might need to download to get the pen to work properly? There are none on the Asus page for this model.
