Please don't hurt me if I mention something that is already known, I'm too busy to follow the whole thread.
I opened a new book. In CV I replaced the existring Paragraph (Deleting nbsp; first, typing the rest) with <p>& bullet; xxx</p> (The text after the entitiy dosn't matter). Switching to BV, the bullet is shown correctly. Switching back to CV and save the book, the line has changed into:
<p>&bullet; xxx</p>
I guess, something is going wrong...
