I seem to be having a problem with the 'Render > Lighting Effects' feature. It works, but not the first time I use it. I can go in, set the controls how I'd like them, and click OK to apply. The effects will remain for about 5 to 10 seconds, and then it will revert to the image I had before the lighting effects were applied. If I repeat the process a second time, the effects will remain in place.
I'm using CS6 via Adobe Creative Suite on a Windows 7 operating system. Any ideas?
