Recently, there have been two cases reported where a font was not displaying correctly in the XMLmind XML Editor and in the default PDF output. In both cases it was on Windows 7 and in both cases the user had installed a new version of the font in question. It turned out that there were duplicate instances of that font installed. (Why Windows 7 allowed duplicates, I have no idea.)

The solution was to get a tool like TypoGraf to see what fonts are truly installed, find the duplicates, delete them, and re-install the one version of the font desired. TypoGraf can be obtained from http://www.neuber.com/typograph/index.html. Please note that it is crucial that you run TypoGraf as Administrator when you try and delete a duplicate font. If you do not, it will look like the font is deleted but it will not be.
