I am currently using IE9 and Vista Home Premium. I have two user accounts, my own and my wife's. In my account I can add, and organize favorites. In my wife's user account I cannot add favorites at all. When in her account I can use "control D" to bring up the box for adding favorites and it will even tell me that the favorite already exists and would I like to overwrite it. This was also a problem in IE8 so it's not new, but the wife is complaining that she can't save her favorites.
