I'm using FontCreator 6.5 professional. I have two fonts in the same family, and in "naming" I've given them the same Font Family Name, and in Subfamily one is called Regular and the other is called Italic. But when I drag the two .ttf files to the Fonts folder in windows, only the Italic one is listed, and they aren't combining. But if I delete the Italic version from Fonts, all of the sudden the Regular shows up. I've checked in FontCreator and they each have a Unique Font Identifier.
What can I do to get Windows to see them as two versions of the same font?
