I create protected forms in word for clients to fill out requests. I send
them a copy of the original, they fill in the form fields and then "save as",
attach their completed form to an email and send it back to me. I'm not sure
if the problem I am having is a result of my ignorance of creating forms in
Word or if I have just hit a limitation of this software, but here it is:

Even though my form is protected and even though limit the number of
character spaces per text form field, I find that if a user presses the enter
key while in a form field, they can reformat the entire document, creating
extra pages, enlarging tables, etc. The original document is still protected
but they can simply "save as" and all of their reformatting will be saved.
Is there a way to REALLY protect my document so that no matter what key a
user presses the document will not reformat? I hope this is clear and I hope
someone can help.

Sincerely,
Max
