[Ripplinger]

I'm stumped as well then if you even went back to default firmware. While I had the book loaded on the reader, I even searched for "quinsy" and found it just to test that specific word since everything else was working, so I'm certain I was using the dictionary in the same paragraph as you're having the problem.

Hopefully it'll never happen again or someone else can come up with some reason.

Also, the Kindle version when converted by Calibre doesn't have any odd formatting issues at all, no weird gibberish anywhere that I've found yet.
