#18 Hints Missing in Release Build

[MO_Woinem]

Hello,

I have created a font and added a lot of hints to make
it look better in the smaller sizes, and it looks good
when I build a test true type font. But when I build
the release version, all the hintings disappear, and
the small sized letters look as ugly as before.
Are there any suggestions what I may be doing wrong?
