Footnote number not superscript ?

Hey all,
A customer calls me with an issue that I've not yet seen before. He is running Word 2003 on a Windows XP box, and has never had this issue before, and still does not have it on any documents except this one. He will select the text he wants to create a Footnote to, does Insert | References | Footnote, and when it places the number on the selected text in the body it is not superscript! The number in the footnotes section is superscript though, and when we select the number and choose Format | Font we can set it as superscript. The main question is: Why does it not automatically super-script it? :-P

Thanks a ton in advance
