[Chimera-users] loading pdb files

I have a series of pdb files that I am loading into Chimera. How can I get each file to load as a backbone structure with a different color for each? I used to be able to do this, but when I loaded a newer version of Chimera it no longer works. I am sure that this must be a preferences issue, but I can't figure it out. Thanks! John John M.
