I've had my Surface Pro 4 for a few months, and it has mostly been going well. Today, when I went to close a tab in Chrome, the mouse pointer stopped responding, and is now hovering in the top left corner apparently constantly "clicking" up there. Keyboard mousepad does not respond at all, touch screen erratic at best. So far I have tried: Restarting Shutting down entirely and turning back on Changing "snap to" option for pointer Removing keyboard Unplugging computer Does anyone know (a) how to fix this, (b) what causes it, and (c) what I can do to stop it happening again? This happened once before, 2 or so months back, with the top right corner, so I'm definitely concerned with how to prevent it, rather than just fixing it for the day. Thank you!!
