Can't use the crop tool
I perplexed:
I pull a side bar of crop tool, and I would think only the side would push in, but the while image gets effected. PS, increases or decreases all sides.
Also, I can't understand why I'm pulling a side and the background is moving around.
Is there an option to use a old legacy version of crop?
Maybe I need a manual on how to use the crop tool. It used to be so intuitive. Thanks.
