Recently I noticed that the left click of my trackpad has a much more mushy sensation than before when clicked, and much more so in contrast with the right click. I don't click the left button often as I use tap and double tap for click and right click mostly, I use it probably 10 times a day or so. I got my mac 4 months ago. Anyone else experiencing this? I'm scared this might be a precursor to future trackpad problems. Thanks!
