This afternoon I did a content-aware move in a photo, and now I cannot change ANY of the tools; the menus don't drop down, and repeatedly hitting the shortcut keys does nothing. I don't think an upgrade occurred during the action but an not sure. What to do?
First, does the application freeze or do the shortcuts quit working? Can you do other actions via a mouse?
Second, do you get this problem every time you try to do a Content Aware Fill? Or did it happen just once? Does it happen with just one file or with any file?
Third, are you using any third-party pointing devices such as a mouse, trackball, or tablet? I ask because often these devices co-opt keyboard input. It's important if you have any of these to make sure you have the very latest drivers.
Let's start with these. I'm available to do a web-hosted screenshare to get to the bottom of this problem.
