Correct. That's why, as a part of the process of creating a Mobi file from a BD one, I do a global replace of:

<DIV >&nbsp;&nbsp;&nbsp;&nbsp;</DIV>

with

<BR>

Note that this "bug" depends on the version of the Mobi Reader. The CyBook displays the "<DIV>....</DIV> correctly as a blank line. The Windows Mobi reader doesn't.
