Hi Vis, It's OK -- I'm glad you found the solution! Showing only the side chain is "smart" enough to include a bond to the backbone CA atom, but (as you saw) not the bond from the proline sidechain to the backbone N atom until that N atom is also displayed.

I'm very sorry, I take my question back. Actions->Atoms/bonds->Show will do the trick. Vis
