Thanks, Sergey. Guess I should have looked, but this seemed quite counterintuitive, so I figured it was a bug or maybe something I was doing wrong, but not seeing. Also, I suppose during past trace sessions I've either never encountered the particular situation or didn't notice it (because I was clicking Skip Over, perhaps). Thanks, again.
