If you are using Office 2007 in an environment where everybody else is using Office 2003, you might have already set Excel or Word to always save to 2003 format, but what about when you create new documents using the New menu?

In case you aren't sure what I mean, just right-click on the desktop and choose New from the context menu, and you'll see Microsoft Office Word Document in the list, which creates a blank .docx file.
