Reply To: Widows/orphans incompatibility between CS4 and CS3

There is a slightly more focused grep expression in this Link (it makes the space before the last word in the paragraph no break).

Unfortunately, text can always reflow when moving from one version to another (especially backward). That's why I like the “don't reflow text until it gets edited” feature in InDesign. Everything is (or should be) locked in place unless you go in and change something in the story.

Note that Blatner Tools (for cs3 and cs4) also has a feature that can find runts for you automatically. (The proper word is not widow or orphan, it's “short last line” or “runt”).
