will not refresh the image until I move it or go to another viewer and back.
The layers panel refreshes for example but when you turn off layer visability on a given layer or make a change to a layer that change doesn't show in the image pane - until you move the pane or leave the pane and then reselect it. Help!
Was helpful comment but I have tried that already! Thanks though!
Try to reset preferences. Start PS and immdiately hold down Ctrl + Alt + Shift keys. You should get a reset window. If you see splash screen you are too late.
