They're always "improving" Windows -- and "Office2007 is no longer
supported." I discovered that when I tried to look something up in
the Help menu and it refused even to consult the on-disk version
of Help, which has usually been adequate (there was a way to tell
it not to look on line for help). So they may have disconnected
anything that goes directly from Windows to Word2007.
I can't move up even to Word2013 because the Bibliography Tool is
not compatible with my customized reference "templates" (and also
the icons on the QAT are bigger so I can't put onto it all the
ones I need).
