Thanks, Frieda and Eric! All this seems to work splendidly on the Intel-flavored Mac that Santa brought. Stereo users will note that Jmol still has its cross-eyed and wall- eyed viewing reversed. Select one (Render:Stereographic:Cross-eyed viewing, for example), you get the other (Wall-eyed, in this case). Cheers!
