Ah okay. Wouldn't have thought of changing it there, although the 'regular' Calibre was fine. I'm seeing that it must be the upgrade, because I changed the font to check the difference, and the original default I had (MS Shell Dlg), which I never changed before, was gone from the list afterwards. Now I have to find one similar that I like

. Since all of Calibre is now affected...maybe I can find that font somewhere...
