Nagios 3-D Map

Hello to you all

I´m trying to make the 3-D status map work but I´m having some problems. I´ve installed a VRM Client: freewrl v 1.19.2 fedora core 6 and I have my javascript working properly. But everytime I access the 3D Status Map, I see everything black and I can´t change any of its “Preferences” features.

Can anybody help?
Thankx
