It looks like samba is doing the correct thing. However they may be storing the short filenames somewhere or I may just be lucky not to hit the hash collision.
They are not storing the short filenames anywhere permanent. Samba does keep a cache of the last 50 (by default) name manglings on a share. You also may be getting lucky. Like Jeff, the app doesn't produce a failure under Wine for me, either.
