Changes in the way the brush tools work. Now you can't use all the brushes with all the tools. Most brushes only work with certain tools (eraser, brush, clone, etc). Whose bright idea was that? A big step back in functionality!!!!! Raise the price and screw up the tools. Way to go Adobe. A least train your tech support reps to recognize the issue and not waste an hour of my time. Why in the world would you make this change????
