[Chimera-users] Proline sidechain broken (with backbone as a ribbon)?

Hi, I really like the default view of a loaded PDB file, where the whole protein is shown as a ribbon, but also the sidechains next to the heterogroups are shown. Proline shows up in this representation as a sort of rhomboid (or kite) shape, which is okay. However, I cannot achieve the same effect for proline when I select proline manually. If I do Actions->Atom/bonds->sidechain/base->show, the proline sidechain appears as a broken rhomboid, which looks more like a hook, i.e. a one of the bonds is missing to close the loop. How do I obtain a "closed" proline sidechain look? Thank you, Vis
