Camera Raw 13.0 and Wacom Intuos Pro medium

Hi I am having trouble with my Wacom Intuos pro medium/pen working with the new Camera Raw 13.0

I have downloaded the latest drivers for this tablet but it is still not working.  I cannot move the sliders but I can open the various tabs by my usual clicks!  Also just tried my mouse and that's not work either!

What am I doing worng?
