Would someone in the Xith3D group update the webstart libraries to use the latest version. This one is a big update as it allows custom pixel format descriptors in OSX. Prior to this , the PFD was hardcoded. This was something that I knew I needed to fix that had been sitting around in the original port - but I just never got around to fixing it until this week.
This should get rid of some issues that may be showing up in OSX versions of Xith3D demos.
