--- Comment #15 from Rosanne DiMesio dimesio@earthlink.net --- Yes, it works for text, even when the font is Cambria Math.
There is still a problem with fonts from equations inserted using the equation tool, but that's buggy in Windows, too, though in a different way than in Wine. That should probably be a separate bug.
