[PyMOL] Atom Display problems

[Page, Rebecca]

Pymol Users:
 
I have three superimposed proteins in a single pdb file; each protein has a 
different chain ID.
I want to display residue sidechains from all three proteins simultaneously, 
but I can't seem to prevent pymol from drawing bonds between different chain 
ID's atoms, so it ends up looking like a jumbled mess.
 
What is the easiest way to get around this? 
Is there a command I am unaware of? 
Or is my only solution to read them in as separate pdbfiles?
 
Thanks in advance for your help!
