I need to have several workbooks open at once, making changes to each separately, flipping back & forth, etc. Now that I have MS Office 2007, I can not find a way to close all the workbooks at once, saving changes to all - "yes to all" button is not there when I close. Can you help me find a way to do this? It is very frustrating to answer "yes" to each of the 30-some-odd workbooks I have open.
