There is no doubt in my mind that Daves problem is a real problem. I experienced almost exactly what he is going through on more than one occasion with high end 3d apps. LightWave is one if anybody would like to know. I was pulling my hair out. On the phone with tech support everyday and they could not figure it out. Then somebody on one of the LW lists found the solution. It actually was simple. What I am trying to say is that if we work together we can help solve others problems whether it be tuts our discoveries, etc. This is a powerful program that actually rivals the best. I expected many bugs but have been very fortunate. Things are working well here. So lets try to help others that are having problems. Ron
