I am using the automatic TOC feature in Word 2007 to create a table of
contents for a document with 4 different header levels.  The headers are
auto-numbered (Ex. 1, 1.1. 1.1.a, 2...).

My problem is that intermittently the table of contents will split the
header number apart from the header topic... and both items will be shown
separately on the table of contents (and with the correct page numbers).

I have attempted to retype these headings, examined the TOC code, adjusted
the style... and done everthing else that I can conceivable see as the cause.
However; I still have not been able to resolve this concern.

I'm hoping that someone out there, smarter than I, might have some
suggestion that I have not already tried.

Thank you in advance for the help.
