Linked Excel files change size when updated
 

I have linked Excel files in a Word 2003 document. I put them there by
copying, using Paste Special, Paste link: Microsoft Office Excel Worksheet
Document.

I have to resize them from the original after I paste them (to approx. 75%)
of their original size.

After saving and then re-opening the document, when it updates the links,
each Object changes size (getting smaller) and does not adhere to the aspect
ratio. If I update manually, it does the same thing.

How can I get them to stay the same size through the update process?

Thank you!
