@Doug Robbins: Thanks much for your generous & prompt offer. Unfortunately, I can't share the document, and haven't the time to try to generate one that will show the problem. (Similar to OP, a new document doesn't.) I'm satisfied with getting any updates
this thread might provide.
It would be nice to get confirmation of something that is intertwined with the problem I described. It seems that F&R cannot find letters in equations unless formatting has been applied to them (including
removing the italics normally applied to variables). Is that true for others? (Sorry if that amounts to highjacking this thread.)
@JB Morrison: Although I've had some success reaching Microsoft themselves in the Excel Community, I'm not sure how closely they monitor this one. Be sure to register your complaint with the smiley/frowny menu in Word, which I've been told is the most effective
way to report a bug (versus troubleshoot a problem).
