I have just discovered that AutoSave in Word 2010 is set to save every 10 minutes, which I believe is the Microsoft default. However, I am certain that I had changed it to something a lot more frequent, like every 3 minutes, and I never deliberately changed it off of that. What could have made it revert itself back to the default, and is there any way of being notified when this happens, or of being asked to confirm such a change before it is done for me? I want my settings to stay the way I've set them, without having to frequently reconfirm them.
