Troubleshoot page and section breaks in Microsoft Word

This can occur after a cross-reference to a table or figure. However often you remove the break, it reappears on next loading the document. The reason is always (as far as I know) that you have inserted a manual page break immediately before the caption that is referenced. The solution is to separate the page break from the caption - ie, by pressing Ctrl Enter at the end of the preceding paragraph or by formatting the caption paragraph to "page break before".
