I am running Windows 7 and using Office 2007. On both Word and Excel Options I have selected the option to show recent documents, but every time I reboot the computer the recent documents list refreshes (empty). It occurred to me that perhaps something in my Norton Utilities "Clean Up" function, which I use regularly, was interfering with MS Office's retention of recent documents. But after removing any mention of recently viewed documents from the "Clean up" options, the problem remains. Any idea?
