I'm talking on the order of a thousand. There was a bug in R3 servers for wide lines which would terminate the DrawLines request at the first pair of coincedent points. If you were drawing zero width lines, then I don't know off-hand what would cause the troubles you were seeing. In any case, R4 servers draw lines much faster than R3 servers, especially wide lines or zero width lines in color (which are now substantially faster than monochrome). Keith Packard MIT X Consortium
