When I open lightroom and look at any photo in the library module, the screen has a strange overlay, when I move the picture the overlay is stationary. I figured out there is some kind of transparent version of the text document I was working on previously, almost embedded into the background of lightroom. Any idea how to eliminate this? It's the strangest thing. I'm on a Mac.
I am not quite sure of what you are explaining, could you post a screen shot of what you can see in Lightroom so that we can understand the issue more clearly.
