I am trying to change the way FontStruct fonts are displayed and uploaded into my Mac FontBook.
This is what I get, when I double click on a Fontstruct Font.
This is just before FontBook fully opens.

Every other font display the full alphabet.
So I uploaded the font into FontLab, and in the section Font Info> Additional Opentype names was this:-

So I deleted it all, like this:-

and clicked Apply. Saved the font, and reinstalled it.
Double clicked on the file again, and I still get this:-

Also when I'm in FontBook, and click Preview > Sample, I still get this:

Every other font displays the full Alphabet, upper, lower & numerals.
What can I do to change this so it displays properly?
It's driving me crazy.
I've cleared the Font cache already.
It's only really happened when I installed Snow Leopard recently.
