I was using the nanotube builder and created 3 types of nanotubes. I had two problems after I built them:
1. I went into select ->add named selection it did not show up in the projtree for easy reselection. I tried settings configure Avogadro and was not able to see the named selection there. I am using windows 7.0
2. I tried to use the click to measure iconF12 to measure the distance between two atoms of the nanotube. Again I was not able to select the two atoms to indicate what distance I was interested in. On clicking the atom only FPS number in the view box changed.
