On my 2013 13" Air, I am getting some phantom clicks, as in light touches on the trackpad are resulting in clicks. I always have my thumb down on the bottom of the trackpad as I scroll with my index finger. I am certainly not pressing hard enough to "click". This just started today - so I wonder if it is a hardware problem. No, I do not have "double tap" to click enabled. Nor have I changed any of my trackpad settings. It's very annoying.
