Last week, I brought my MBP 13" 2010 into my local Apple Store for a weird clicking noise in the trackpad. They replaced the trackpad and then gave it back to me today. I was just wondering, was there always a tiny little opening all the way on the right side of the trackpad? It's only think tiny little thing on the right side where you can just hardly see into the computer. I don't think I've noticed it before, but I could just be very picky. If it's not supposed to be there, then I'll bring it back in for them to adjust the trackpad. Help is much appreciated
