I have a user who is using Word 2010 on her work computer and when you click ctrl-s or select save from the file menu it is defaulting to saving them as the auto save backup file ASD file extension. I thought for sure she had the "Save files in this format" set to ASD from the File -> Options -> Save pane but ASD is not an option! It is set to docx still. Has anyone seen this behavior before? How do I get it to save as doc or docx by default again?
