3D Problem

Hi there

if i try to run the P4_01 example from Ugo Taddei's Tutorial i always
get the error below.

Any ideas what is wrong or hints where to look closer?

Thanks in advance.

Java 3D WARNING : reported GLX version = 1.2
    GLX version 1.3 or higher is required
    The reported version number may be incorrect.  There is a known
    ATI driver bug in glXQueryVersion that incorrectly reports the GLX
    version as 1.2 when it really is 1.3, so Java 3D will attempt to
    run anyway.
