Recently my Vivotab RT generated this issue where it won't accept swipes. Swiping to unlock the lockscreen the background stops where I lift my finger and doesn't swipe all the way up. Also, when this occurs, any edge swipes to bring up the charms bar or any menu inside an app doesn't work. Rebooting the tablet fixes it for a while but it always comes back. I have a Ghost Armor screen protector on, but it's been there since February and never been a problem. Next step would be to factory reset the tablet. Has anyone experienced this issue with this device?
