Hello,

in my document, I use cross-references to figures. In the cross-
references fields I use the \*Lower switch argument.

When I send this document to a colleague, all cross-references using the \*
Lower switch argument gets the following error:

Erreur! Argument de commutateur inconnu.

which translates in english as:
Error! Unknown switch argument.

I understand the error message but this field is correctly displayed on
my computer and my colleague did not modify my document. And if I erase
the \* Lower argument (which is now a \* MINUSCULE argument because he
uses the french version of office) everything works fine in his document.  
However, when we look at the Office Help in french the \* MINUSCULE is a
valid argument...

As anyone encountered similar errors before (and solved them)?

My word version is Office 2004 for macintosh in english and my colleague
uses Office 2003 for Windows in french (which explains the error message
in french)
