Hi Niels,
Is there a way to send you email? I want to send you a video (for your perusal) re: losing pen pressure when 1.) Opening AP; and 2) leaving AP, and switching to another software, apps or browser, then going back to AP. But the screen recording I made was just about when opening AP. Although the Add/Insert Blank drawing is still the solution for me in getting back the pen pressure to work.
