I'm so lost! None of my Photoshop tools will work. I have checked all the reasonable possibilities and have reset the preferences using the Ctl Alt Del function when opening Photoshop. I first discovered this when my clone tool wouldn't work.
I can't paint, no dodging and burning, nothing. I can select and move and select layers. I am fairly advanced PS user having been using it for at least 10 years.
Anyone have any ideas? I need my Photoshop........
