Hi I have rMBP since launch and this is my first real problem. Trackpad sometimes dosnt work as it should. Two finger swipe to get to notifications is hit and miss. Suddenly three finger look up dosnt work in any aplications (settings are correct) even though three finger drag works. And if I do two finger scrolling in either side of trackpad it sometimes stops working. Is if software or hardware issue? What should I do? Hope you can help. Thanks. Ok right now works every singe swipe except three finger swipe to change desktop and three finger look up. Any ideas.
