[dba-Tech] Word Questons

1. How do I see the properties of a Word document? Specifically, how can I
determine which template was used to create a given document?
2. Once a document has been created, is there any way to switch it to use
another template?
3. How and when can I specify which template to use when I create a new
document?

Background. I have a pair of computers side by side, both running Office
2007. Somehow I did something on my new computer that has changed the page
layout of a normal document. Documents now appear with neither header nor
footer -- no matter which Page Layout I choose, it has no effect. I even
completely uninstalled Office and then re-installed it -- to no avail. I
tried to create a new Word document and got the same result -- no header or
footer. So then I copied a "bad" document from here to the other computer
and opened it, and it behaved the same bad way. I created a blank document,
which opened the "normal" way, then selected all the text from the bad
document, copied and pasted into the blank document, and lo and behold, it
behaved "correctly": the normal header and footer were respected. So I
closed the bad document, and overwrote it with the good version. Then I
copied it back to the computer where the problem exists, and opened it
there, and its header and footer were correct.

Next, I copied Normal.dotm from the good computer to the bad computer,
overwriting the bad computer's version. Then I created a new document and
Damn! It still didn't work!

The final thing I did is copy the good version of Normal.dotm to the
templates directory, naming it normal2.dotm. Hence my question about how to
tell Word to use that version when I create a new Word document.

I'm at my wit's end. Any advice, Word experts?
