You can only use one normal.dotm at a time.

There is a difference between saving a file under a different name (Save As) which keeps the old file under the old name, an renaming a file which results in only one file with the new name.

I still don't understand what you are doing. Could you post a copy of your files: The normal.dotm which came from Word 2007 and had your shortcuts,
The normalxxx.dotm and normal-normal.dotm

You'll need to put them in a zip file (compressed folder) to upload them.

I'll take a look at them; no promises that I will be able to figure it out. Right now I feel like we are two blind men trying to describe the elephant.
