Can anyone tell me how my PS23 lost its preferences by itself in the night when my iMac was asleep (and PS was not left open)? That was a bit unpleasent, as my shortcuts stopped working. I copied a few sets of PS preferences from my Carbon Copy Clone backup until I found the latest ones. The shortcuts were back! However, the color scheme of PS had changed (plus Neural color was off), as well as the contents of some panels, for example, Color Swatches and Brushes. The former I could load back. A nasty thing!
