Trackpad's top right corner acting weird
Hello! I own a Macbook Pro Retina display and its trackpad is acting weird: When i slide ONE finger from the center to the top right corner, it shows my desktop, just like when i spread thumb and fingers to reveal the desktop.
WHat's going on? Why is it so sensitive and how can i fix it??
Please help, this is driving me mad in frustration!!
MacBook Pro, iOS 9.1
