I use Transform a lot when editing photos and have never had trouble. Today, none of my JPG or PSD files will let me transform. The option is greyed out. I tried to quit Photoshop and restart, I tried with old files I've used the Transform options on in the past, but nothing. I did check the Preferences but didn't see any "Don't allow Transform" or similar options. Suggestions, please? I have half a dozen pictures I need to clean up and adjust.
