It's not layers I'm having problems with. I bring up the program, I open a picture and it is immediate locked in place in the center of the work window. I can not move it in any direction. cannot reduce it. That is, I can reduce the image, but I cannot see or work with a second inage- the "Frame" around the first image remains the same size and locked in place. All I get are file tabs at the top of the screen. Right  now, it's impossible to see two or more images at the same time.
