I have had this error for several different reasons. If I remember correctly, one of my bugs that caused this to happen was when a transformation or loadmatrix resulted with NaN as an element of the top matrix in the matrix stack. I think a second bug was pushing the matrix stack too many times. Good luck, it's tough to debug when you keep ending up at the login prompt and no corefile has been left! (I did this on a 240 with 3.1F) While I'm here.....I have this bizarre bug that causes the lighting on our SGI to go into twinkie zone. Under a few certain transformations my light source shows up in the wrong place and shades p-gons with an "all or nothing" effect - either pure white or ambient grey at the verticies. Even more bizarre is that with shademodel( FLAT ) I will still get color interpolation across a surface. I must say that I've been talking to someone at the hotline about this and he has been most helpful. -Tim tjh@bu-pub.bu.edu
