#Extra Vertices
Sometimes when working in the 3D editor (v.3), I get unpredicted
vertices and faces suddenly added that I did not draw, even on simple
objects such as the old table and goblet tutorial. These planes
render as well. It's really a mess and extremely disrupting to the
work! Do you have any idea what is causing this? I never experienced
it with v.2. (386DX w/ 8 Mb RAM).
