I've merged 2 PDF docs. They have been filed and are no longer on the desktop. However, I am left with a single generic PDF icon on my desktop. The icon shows the Preview picture with letters PDF below the picture, and right upper corner is folded down. The name below the icon is the name of one of the 2 PDF docs that I had merged (e.g., xxxx.pdf). If I highlight the icon and try to Get Info, nothing happens. I can't Open the item. I can't move it anywhere else on my desktop; it's "frozen" in place. When I try to drag it to Trash, or Move to Trash, I get a message window with the Finder icon: "The item xxxx.pdf can't be moved to Trash because it can't be deleted". Any ideas on how to get rid of it?
