--- Comment #10 from Rosanne DiMesio dimesio@earthlink.net 2011-08-01 08:46:36 CDT --- Disabling Protected View (File=>Options=>Trust Center=>Trust Center Settings=>uncheck everything) enables Excel, Word, and Powerpoint to open and save xls, doc, and ppt files, without the patch. Disabling has to be done separately for each Office app.
