Well, with the new "smart" display, Chimera will hide atoms that it  
doesn't think are "interesting".  Perhaps the Xenon atoms are being  
considered uninteresting, in which case you would need to display them  
explicitly, i.e. "disp Xe", or Select->Chemistry->element->other->Te- 
Zr->Xe followed by Actions->Atoms/Bonds->show.
