How do I avoid re-formatting outlines when toggling between docs?

[sreiser54]

In Office 2000, if I have multiple documents open, and I am creating an
outline format, and I either underline, bold, or italicize the first word of
the sentence, invariably that sets the format up so the next line comes up
automatically as bold, underlined, or italicized.

Ex.: I format it like this:
I. <<u Brown v. Board of Ed. u>> This decision....
A. <<u whatever is here automically is underlined>> when i toggle to
another document, get my info, and return to the first document.

Any help would be appreciated.

Thanks
