Yes, I believe so. Version number is 5.0.4.321. I have found that the problem seems to be in the light set I am using. I created that set in another scene, saved it and then used it in the current scene which is where I'm having the problem. If I use that light set in my test scene with Don and Judy only, I also see the problem of no shadows. If I open a new scene and create the shadow light from scratch, the shadows look ok. However, it doesn't work to just delete the lights and recreate them. Whatever the problem is, it just keeps coming back when you do that. It must be some parameter in the light set definition that persists even after all the lights are deleted.
