Corrupted normal.dot in Word 2003

Question

The opening template on Word 2003 (normal.dot) has the insertion point at the very top or sometimes off the top of the page. I've tried resetting margins and paper size. I got an old document, made a template and replaced every copy of normal.dot I could find and it fixed it for about two weeks and then it came back. The same happens if I use other templates now. I run Norton 360 regularly and it seems clear. I'm stumped. All suggestions gratefull received.Many thanksMartin Akehurst
