Problems with FBX Exporter and grouped props

mario.cicalese2_d6b65131db

Hi, I was wonder if there is a workaround for a problem that I have when I try to export in FBX a character that has something grouped on it.

For example...

The hair here are a prop grouped to the head http://img571.imageshack.us/img571/6359/a2i3.jpg

When exported in FBX, the hair are no longer in position http://img22.imageshack.us/img22/9239/w0yn.jpg

And this happens with every prop grouped to a character...

Any suggestions for this problem, please?
