I had panels. Where are they now?
Okay, I’m pressing the F key to cycle through the screen modes. I’m in Full Screen Mode and poof, my panels disappear. Where are my panels? Tapping the F key twice changes from Standard Screen Mode to Full Screen Mode (View>Screen Mode). In Photoshop CS4, the panels disappear in Full Screen Mode, focusing on the photograph. Press the Tab key to reveal the panels.
your pannels in full screen mode are hidden to the right, all you have to do it hover over the right of your screen and then they will appear.
