Valid XHTML strict messed up in IE Mac

I have a page here that validates as XHTML 1.0 strict that works fine in
Safari, Mozilla, and IE for the PC, but in IE 5.2 for the Mac it's all
messed. Text that is supposed to be inside a table cell shows up
outside, making it nearly illegible. (Also, the page background color
does not render -- it's just a white background.)

The page is here: www.afwh.org.

This is the CSS: www.afwh.org/css.htm

Any help would be greatly appreciated!

Thanks mucho,

E
