Plese HELP - Error when saving file!

[LindaBig]

When I try to save a file I am getting an error saying the file is in use. What is happening!!

Are you in Editor when this happens? What exactly did you try to do - File>Save or File>Save As? What specifically does the message say? Then we can help better.

The only way I can guess this would happen is you have both photo1 and photo2 open, and when you go to save photo2 in the save dialog box you actually click on the name of photo1 and it won't let you save over it because that file is open and in use. If you try to save photo2 on top of photo2 it will just replace it, or it may ask you if you want to replace it.
