Photoshop question, Rounded Rectangle Tool
 

For some reason my rectangle tool seems to have permanently turned square. Any idea how to make it rectangle again? It's confusing the hell out of me.

There is an option to make the tool a square instead of unconstrained. To make it go back to normal, you have to click the little downward arrow next to the star shape tool on the options menu at the top and choose Unconstrained from the menu. I hope that makes sense.

or try "Shift+U" :thumbsup
