Amaya and CSS

Is it just me or does Amaya not support CSS fixed or absolute positioning?

I have a web site that I am working on at:
home.golden.net/~mohrgan/RagingAsianWomen/RagingAsianWomen.html
that validates as xhtml 1.0 and CSS, but does not display correctly in 
Amaya, but does in FireFox, Mozilla and for that matter in Internet 
Explorer.

Interested in your thoughts
