Hello, I know this issue has been discussed before, but I've never seen an answer that works for me. On my Mac Pro we have installed Snow Leopard and all of the fonts in a folder became grey Unix exe files that can't be opened with Fontbook or with Suitcase Fusion 3. Inserting the back up font disk has the same result. On the other computer which is a G5 running OS X 10.5 those same fonts work fine as does the back up font disk. Any suggestion?
