Hi Danny,
It should not make any difference whether you are using the graphical interfaces (dialog windows) or commands.  I only put commands in my example because it is much less typing to describe.  

As I mentioned before, just make sure that in the Coulombic coloring dialog, you have chosen all of the surfaces…. the most obvious reason it might only color one surface is if you only chose (highlighted) one surface in the list.
Best,
Elaine

However, if that still doesn’t work you can always try submitting a bug report (menu: Help… Report a Bug) and attach the session so we could try to reproduce it.

>> My name is Daniel Heller, and I am working with Helen Berman at Rutgers University on a PDB project.  We are trying to analyze multiple DNA binding proteins simultaneously (via matchmaker) and looking to visualize the surface electrostatic potential of each structure as a tiled picture. We are deleting the nucleotide chains for all proteins when complexed with DNA.  However, I am only able to get the surface electrostatic coloring for one structure (the reference structure), subsequent structures will not apply the columbic coloring after i hit apply, they just maintain the monotone default surface structure .  Could you please help me with this issue.
