reset preferences. Start PS and immediately hold down cmd option shift keys. If fast enough will get a reset window.
Thank you! When I did what you said it asked me if I wanted to reset everything. So I was wary of resetting all my tools so I looked that up and ended up resetting the crop tool only.
Basically, I did what was on the thread below. I just right clicked the chosen tool, in this case the crop tool, and clicked "reset tool" And it fixed it. I would've never gotten this on my own. Thank you again.
Follow the steps below to fix.
Launch Adobe Photoshop CS6 and click on the Crop Tool on the left hand side.
On the top left, reset the crop ratio in the drop down to “Original Ratio.” This somehow resets the crop tool.
You should now be able to crop again.
You will probably want to then set it back to “Unconstrained.”
CS6 so far has been the buggiest version of Adobe Creative Suite to date. Especially if you are running on an ATI GPU.
