MS Office Word 2007 paranoia

After a crash, MS Office Word 2007 messed up my documents' formatting and stopped to highlight the special fields and spell check.

Also, the Document Map view become useless... Turns out that it has the "intelligence" to mark short phrases as "titles", for instance captions for figures and tables.
To fix it and remove the unwanted titles, make sure the caption style is formatted as "body text"  instead of as outline "#level" - click in a caption and press Ctrl+Shift+S, then click Modify... Click Format - Paragraph, and in the Indents and Spacing tab, check the Outline level drop-box.

The spell check highlight was restored by deleting the registry key HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Word (MS Article ID: 822005).
