MS Office 2007 Saving word in 2003 .doc format.

[Baffled]

Hi,
We have set all of our OFFICE 2007 installations to save documents as "Word 97-2003 Document (*.Doc)" format by default. This was done in the Word Options/Save Menu.

Some of the setups, however, seem to lose this and revert to "Word Document (*.docx)" format between Word sessions.

Has this been noticed before? If so, has anyone a solution to this problem?

Thanks

Have you done any updates on other machines? May be the office update change defaults, check that save as .doc is still selected by default when saving.
