Word 97 docs in Word 2000

I would highlight the entire document and click the underline button once and then again to turn off the underlining. Then highlight the text she wants underlined and apply the underlining again.

Hope this helps!

Please check the font format sometimes the user may have hit the effects check boxes by error.
To do this open word then format on tool bar
then font.
I hope this helps and Good Luck

Is the text actually underlined, or are there lines drawn (with the Line tool on the Drawing toolbar)? If you click on one of the lines, does it select it? If so, you can move the lines to the proper position, or delete them and use the Font Underline command.

Just a wild guess.

A possible solution can be changing the line spacing. Format | Paragraph | Indents and Spacing tab. Play with the options available in the Spacing section.
Hope this is a help.
