Problem with saving file as DXF

When I save a DWG file as a DXF, then edit it and save it again, it defaults to saving as a DWG. Then I have to change the file type back to DXF and save (and get an error message about saving a file that already exists).
Is there any way to save as a DXF so that it stays a DXF subsequently?
Apart from being time consuming as I have a lot of DXFs to deal with, there is an opportunity for errors to happen.
