Text from Microsoft Help as below on the subject of default Language settings.
You can change your default settings in Microsoft Office to have them match
the default settings of a different language.
In Microsoft Windows XP, on the Windows Start menu, point to All Programs,
point to Microsoft Office, point to Microsoft Office Tools, and then click
Microsoft Office 2003 Language Settings.
In Windows 2000, on the Windows Start menu, point to Programs, point to
Microsoft Office, point to Microsoft Office Tools, and then click Microsoft
Office 2003 Language Settings
Click the Enabled Languages tab.
In the Choose the language that defines default behavior in Microsoft Office
applications box, select the language you want, and then click OK.
A message appears describing the effects of the change. To continue, click
Continue and lose customizations.
Does this help?????
