Is there a way to disable the pinch open and close feature on a MBP trackpad? I swear, its going to put me in therapy. Every time I need to scroll through massive spreadsheets for work, if my fingers separate by even a hair, the trackpad reads it as a pinch, then the document suddenly balloons to massive proportion or shrinks to infinitesimally tiny print. Seems there ought to be a simple way to turn the thing off, but for the life of me, I cant find it. Help, please? Thanks!
