Hi Ernie- Here's something else to try. In the Edit->Preferences dialog under the Formats & Data tab, set the Thread Count for Rendering to 1 and see if that clears up the problem. I ran into an oddity on my system with another grid that produced some weird isosurfaces and setting that to single threading cleared up the problem. Let me know if that works for you and we can look into this further.
