I logged in to my old Mac to get the name of the file back (duh) and returned it to the old name because I felt like a twit, all this before I got your email.

Then when I tried the command + w, wow, it worked. Yes!!!! Such a simple solution. Thank you so much. It is wonderful that there are people out there like you to help the lesser beings amongst us!
