I just recieved an e-mail from CL, and they possibly explaind the background problem, but I'm still having lighting anomalies. I have "Rolled back" to Service Release 3 myself for the moment because that still works. So hopefully now they are aware of these problems and will release a patch or offer some solutions. Larryma, if you haven't already, please submit this to the tech support at CuriousLabs. JamesSF
