Word changes entire document formatting

[Robert Willhite]

In Word XP every time I try to apply a style i.e. Bold to a single word, the
entire document changes to bold. If I am trying to select a series of lines
and change them to a numbered list, the entire document becomes a numbered
list. This has only been occurring since the last automatic update for
office XP.
