I'm using Excel 2007 and often when I open an excel file and then close it (without touching anything or changing anything) the "Date Modified" is changed to the current date. Meaning the file was saved again without prompting me if I would like to save it and changes its date. Is this situation known to anyone? How can I disable this option? Now what happens is that I don't have the original date the file was saved on and it can be meaningful. Thanks! A.
