This is crazy! I am in the middle of sketching and all of a sudden my Surface 3 loses Pen and Touch input. I've had four different tablet PCs and I have never had the problems with them that I have with the Surface 3. Of course all of them had the limited connection wifi issue once in a while, but never have I lost Pen and Touch! And I never had to worry that plugging in an Asus, Samsung, or Motion Computing Tablet PCwould result in draining the battery instead of recharging it. I can deal with all these issues but not losing Pen and Touch while using it. Even the Asus VivoTab Note 8 which had many problems never had this problem. Checking the Event Viewer doesn't help (Or I don't know what I should be looking for), but honestly I'm getting fed up.
