In the Edit Replace dialog, click on the More button and with the selection
in the Replace with control, which should contain the lower case version of
the name, click on the Format button and then on Font and click on the All
Caps box so that under the Replace with control you have "Not Small caps,
Not All caps", then execute the Replace.
Please post any further questions or followup to the newsgroups for the
benefit of others who may be interested. Unsolicited questions forwarded
