Carousel navigation missing

Hi,
I'll start out by saying this is a great module! Where can I donate to your efforts!
Unfortunately I have a small problem that I can't work out. I have a functioning carousel but it has no navigation. The jcarousel-prev/next do not seem to visable in Firebug. Any thoughts on why this is? Also, could you post a screen grab or list of options you have enabled on your demo site? (for drupal 6)

Cheers.
