Can you post a screen shot so that we can get a better understanding of your problem?

Bob greetings

I would love to but wouldn't know where to start, as I said it is occasional and not that often, but annoying when it happens, oh yes I am sure that I am in the wrong place I am using CS6

I will move your thread to the Photoshop forum for you, jonh_now.

That usually means your image doesn't have a Background layer.

If your image doesn't have one you can create a background layer from

any selected pixel layer by going to Layer>New>Background from Layer.

I hadn't thought of that. from a cut out, layer "0" yes thats sounds great.

I have just tried it , it works perfectly, problem sorted many thanks
