Office 2007 converter for office 2003

[David]

Hi does any one know if it is possible to configure the office 2007 converter
pack to be able top open and convert a docx file but if you click save it
defaults to a .doc

My initial thought was to write some VBA code to force a save on openin the
correct format but I wondered if the conveter can be configured allow the
opening of docx but not allow the saving of docx files, probably a long shot
but I thought I would give it a try.

Thanks
David
