this is a test azw3 I created that only has the phrase the quick brown fox... in four styles, regular, italic, bold, bold italic. It opens fine with calibre viewer, but voyage with 5.10.3 won't open it. I thought it was my custom fonts but removing the fonts folder and rebooting did not do it. Could someone (preferably on 5.10.3) try it out (file attached) and let me knows what happens?

thanks
