Hi DaltonST, thanks for your thoughts... they are probably not the latest fonts, they were from Google Fonts originally, I can update them from the font website on my local machine and re-embed them in the ebook. But I did not think that the fonts needed to be installed on the ebook reader device, as they are in the ebook? I don't have these fonts on my iPad or iPhone for example, but they display just fine in the book.
