I recently upgraded to Windows 8.1. When I go to the start menu on my Asus Ultrabook I use the trackpad 2-finger scroll to move from left to right. However as soon as I stop scrolling and go to move the mouse anywhere it immediately opens a random app (the mouse pointer doesn't even need to be close to said app). It never did this even once when I still had Windows 8. Any ideas on what's happening?
