Understood, gentlemen. Thank you for looking into it. I'll just have to find and add .ttf fonts to my /System/Library/Font folder. I tried that and it does work. I don't need too many, but it means I can't scavenge the ones in FontBook, because one cannot open the contents of .dfonts to get the separate types- Bold/Italic etc. So I'll have to google for fonts. I was just hoping for a more expeditious solution, lazy girl that I am.
Thank you kindly again.
