[Chimera-users] saving images -- wire representation at higher dpi

Hi, I am trying to save higher resolution images that contain some residues with a wire width of 2.  I have noticed that when i increase the dpi of the images, the saved images look different than what is displayed in the viewer -- nodes appear at each atom of the residues that are displayed as wires.  As i increase the dpi of the saved images, the nodes become increasingly exaggerated (of a thicker radius than the wire bonds).  Is this what should be happening?  If so, is there a way to have both the atoms and bonds save with the same radius?  Thanks a lot, ryan
