That's actually why I needed a second step. Replacing ". " with ". " across all is going to usually yield a few where the stop is now followed by THREE spaces. Thus my second Replace of stop-three spaces with stop-two spaces. But where that makes extra work is in the cases within the doc where I actually wanted one space, like "Chris B. Gordon" and "Mr. Paul Wilson."

For me, I generally do all the other revisions in the document first, and try to keep an eye on how consistent/inconsistent the author has been in applying the spacing. If it's a large document and the single-spaces are all over, I may do the Replace All/Replace All sequence. Otherwise, I do a manual Find/Replace and hit Find Next if it's a break that doesn't need replacing.

There are lots of things I wish I could change about the way the department uses Word. For example, all their docs are set up with 0 before and after line spacing, so paragraphs are made by double return. When it comes to having to eyeball a document that may contain small and large tables, text boxes, images, and the like, this makes for some funky page breaks that would be eliminated by using the paragraph spacing. I suspect they may be susceptible to change when the senior partner eventually retires.
