Hi!

This has been sitting in my in-box for ages, so today I finally decided
to test it. I am trying to use it with Pix' nqpoly4 abstraction in order
to get a lot of lines at the same time. But when I do this, I only
get one of the lines existent, the others only appear as the end 
vertices.
Any idea why this might be? And even better, how I might go about 
solving this problem?

cheers,

tim
