I've had my Macbook Pro since mid 2009. It's been great, never had any real problems. Then in about October, I noticed one side of my trackpad wasn't offering as much resistance as it was before. I just ignored it, didn't mind too much. But it progressively got worse, and eventually got so sensitive that I couldn't even scroll without it clicking when I didn't want it too. I was pretty upset, called apple, they told me to send it in and fixed it for free. It was all very nice, orderly, and quick. So I was satisfied. But, lo and behold, it's at it again. I can't believe it. It hasn't gotten so sensitive that I can't use it yet, but I'm very upset right now. I have no idea why it's doing this. It's not really overheating, I have never dropped or hit my macbook. I'm the only one who uses it. I don't abuse it at all. Does anyone know why this is happening? I'm having apple call me tomorrow...but I want to know why in God's name this is continuing, and what should I do?
