Has anyone else had an issue with the touchpad on the new MBP? With 3 finger drag, it rarely engages and I have to press to click, hold, drag (which I hate). It's not my fingers. It works fine on my 12" MBr and my Magic Trackpad (with this MBP, so it's enabled) that I've had for year. Also works on my old 2012 MBA and my wife's old 2010 MBP as well. This is driving me nuts. Anyone else? Any suggestions? It seems like the surface is different. It feels a little more coarse than the 12" which is buttery smooth. The same on the external trackpad.
