LOL, thank you! 
Well, if you see it happen again, I'd suggest stopping to examine the text for character level formatting. Matt and I both work as trainers, do layout work and answer questions here, so we've encountered many of the bugs already and this one is new to both of us. However, if you really think it's a bug, your best bet is to report it here: Tracker. While the Adobe engineering team does scan the community forums for issues, they will definitely see it if you post a bug report. And you can link back to this thread to avoid having to re-explain the whole thing!
I hope your layout goes smoothy from here on out, and bookmark this forum for the next time you run into an issue: Adobe FrameMaker. It may be a little clunky, but we are here and always happy to help.

P.S. I can't recreate the issue with the two-word F/C either.
Thanks a heap, BarbBinder...
Will keep it all in mind...
Thanks for the P.S., too... Just possibly it was caused, randomly, by a two-word F/C. Who knows...
