Crazy cursor on Windows Surface? If you experience a problem where the mouse cursor starts acting erratically on your Windows Surface RT, it just might be a defective keyboard.
From the moment I started playing around with my Surface, I started having issues where the cursor starting moving on its own around the screen, blinking and shaking intermittently. Removing and reattaching the keyboard seemed to resolve the issue, but only for a short period of time.
I took the Surface to the local Microsoft store and showed them the issue. They replaced the keyboard and it resolved the problem. Thanks Microsoft Store – Bridgewater, NJ!
