In my Word 2010 advanced options I have the program set to save backups of previous versions of documents being saved. However, that does not work on some of my documents. When I look at the advanced options for the specific documents that are not having the saving backups occurring, I nevertheless find that "Always create backup copy" box is checked. I don't discern any differences between the documents that are having such backups saved and those that do not. Can anybody help me find a solution to this?
