I have this problem in both Photoshop and Pixelmator. The box that goes around the selected layer for resizing is not there. I've checked the app preferences and everything, but why is this a problem in both apps? Every other app works fine. It's really annoying as I have no way to resize layers! Edit: Nevermind, I figured it out in Photoshop I didn't have Show Transform Controls selected, but I still have the issue in Pixelmator.
