Consider the following scenario:
- You install a localized version of Microsoft Office Word 2007 or a Multilingual User Interface Pack (MUI) for Office Word 2007.
- You set the Office Word 2007 user interface language to a language other than English in the Microsoft Office Language Settings 2007 dialog box.
- You create a document in Office Word 2007.
- You insert an English cross-reference in the document.
In this scenario, the text for the cross-reference displays in the user interface language instead of English.
