Having just modeled a pistol,  I've noticed a strange occurrence when it is shown in the SreeD preview window.  It shows what appears to be a vertice shooting out into space.  In OpenGL preview, as well as the finished render, everything looks fine.  Since I will be putting this model up as a freebie, I wonder if anyone knows of a fix for this?  Or is this just one of them Poser bugs and I should just simply ignore it ?
