I've noticed that JMOL cannot read output files from Gaussian 98 when the NoSymm command is used.  It appears that it cannot recognize the file format.  This seems to be true for either geometry optimizations and also single point frequency calculations.  The version that I am using is JMOL 8, and I am hoping the correction will be in the next version.  Thanks,
