Am I safe in presuming you're using MS-Word as your word processor? If so we should open up a topic in the Chat Subgroup as there are some tricks you could possibly use with Word's own find and replace (whether you're replacing or not) function that would let you find embedded capitals mid-word or capitalized words mid-sentence. It wouldn't be able to distinguish when proper names are involved mid-sentence, though.
