I found this fix http://wiki.logos.com/Fonts_in_my_interlinear_are_not_displaying_properly!_%28Windows_XP_only%29x on the Logos wiki. I too have XP, but I have noticed that the fonts in the LXX/MT Parallel in Greek (not any other interlinear) don't work very well. The two check-boxes that the wiki asks to be checked were already checked. How can I fix my Greek fonts in this particular book?
