Thanks, Miklos, that's sort of how I envisioned it. It seems that Writer 
isn't
just having trouble deleting this special marker (it's debatable whether 
that
is even desirable), but it mistakes the immediately preceding character as
off-limits, and also prohibits inserting anything immediately before that
marker (well, I'm thinking out loud here, but it's giving me some ideas).

Thanks for the nudge. A-hunting I shall go!
