I am running Word 2003.

When ever I try to make a change to the formating of a single line, Word
automatically applies the change to the entire document. Pressing Ctrl-Z
reverts the entire document back leaving the original change I had intended
in place. This is getting very time consuming.

How do I change this? I can not seem to find the setting that prevents this
from happening.

Thanks,
Troy A. Courtney
