It seems that the first and last frame in GAMESS.log files get all  
the MOs in the file associated with them.  Thus in a typical geometry  
optimization, the initial guess geometry has both the initial guess  
orbitals and the orbitals for the final optimized geometry associated  
with it.  The last frame (the optimized geometry) has the same set.

I think the proper behavior would be to have the initial guess MOs  
associated only with the first frame and the final orbitals with the  
optimized geometry.  There is a GAMESS option to have orbitals  
printed for each step in the geometry optimization, so it would be  
good to get the correlation of MO with geometry correct.  Otherwise  
one could potentially have a massive number of orbitals associated  
with each frame.

I noticed this because the list of orbitals in the popup menu has two  
sets of negative orbitals.  I'm not sure whether this has been  
happening all along or is new.  It definitely exists in 11.6 and 11.7.

It wasn't obvious to me where the decision of which frame (atomset?)  
the orbitals are associated with is made.  If the solution is obvious  
to someone please fix.  If not, can someone point me in the right  
direction?
