Can't restore Lucida Grande
I have been having problems that I suspect are related to a Lucida Grande system font. I discovered that Lucida Grande in my System/Library/Font folder is a ttc (Windows) version, so I reinstalled 10.6.8 from my system disk. The same ttc Windows font is there. This does not seem right. How do I restore the Apple ttf font?
