Macbook retina 2014 - Intel graphics
**Short description of error**
My touchpad usually works with two finger rotate and pinch to zoom, something has changed and I'm not sure what exactly which means two finger up/down will zoom and if I flick two fingers across the touchpad I get a kinetic rotation. It means that both zooming and rotating are entirely unusable
**Exact steps for others to reproduce the error**
I have no idea how this happened, blender was running at the time I may have pressed an incorrect key combination or something which has started the problem, alternatively there may have been some kind of system update which has started the problem. The machine has been rebooted and the problem persists, I have also removed all blender application configuration folders and I'm still having the problem, I've upgraded blender from 2.73 to 2.74 and the problem has persisted.
