Hi Noel,
I wanted to get back to you and let you know what happened. I reviewed everything you said and went on a hunt. I discovered there was indeed a size entered in the top bar and it was 1 pixel. I deleted it and everything was fine again.
However, what I do not understand is why the exact same thing happened in PS6 as well? It too was set to 1 pixel. I do not use that box and even if I did, would never set it to 1 pixel. I find it baffling how it was set in BOTH CS4 and PS6.
Thank you for your help.
I will likely be back...
