Have there been any major improvements in the guga &
mrci modules since Molcas 4.1 (e.g. increasing the
size limits in the guga module)?


P.S. I would also like to report a strange occurance
in the mrci module's output:

Don't know what to make of *'s, huge occupations
and absence of occupations?!

my guga & mrci input look like this:
