Same Problem as:
http://www.oooforum.org/forum/viewtopic.phtml?t=65938
Which to my knowledge has not been rectified yet in 2.4 (based on a brief search
of it's release notes).

The problem is that open office does not save my numbering of headers.  I am
using header 2 and header 3 to create chapters and sub chapters for a document
however when I go to insert a chapter or sub chapter after exiting and
reentering my document I find that the number or my newly created chapter or
sub-chapter will always be 1 or 1.1 respectively.

An even worse problem is that i seem unable to reproduce this in any documents
other then the one i found it in, which I would prefer not to disclose as it
contains proprietary information vital to my team's competitive advantage.  So
far at least I know one thing that does not reproduce this problem:

Opening a new document, setting up numbering for header 3 and creating a list of
3 header 3s then reopening that document and attempting to insert a header 3 in
the middle of the list.  That works, which is a problem in that it breaks my
definition of this problem. :S

Anyone got an idea as to how to help make my problem more easily reproducible?
(or how to just make it go away.. i guess I could live with that too ;P )

I will also try upgrading to 2.4 and see if that makes the issue go away.
