When format of text (i.e. boldfaced), entire document changes

[Guest]

I have a wierd problem in any new wor document. When I format a line of text
such as making it bold, my entire document formatting changes. So I lose
bulleted lists, headers, etc. To correct this, I simply use CTRL-Z and the
formatting returns to normal in the entire document as well as the original
text I wanted to format remains bold faced.

Any thoughts on how to turn off this formatting issue?

Thanks,
Steve
