Web site not working in KHTML :(

[Charles A. Landemaine]

Here's the page: http://dev.pcbsd.org/site/
I'm having a problem, and I'd like you to check it also. The page
loads fine in Konqueror, but when I start scrolling, for some reason,
all colors turn black  Could you try it too? What can I do to fix it?
It's standard-compliant code that works fine in IE7, Opera 9, Firefox
2 and Seamonkey.
Thanks,
