ECP calculation of La using Gaussian 98



Hi all,
 When I calculate the energy of La atom, if I change the initial
 orbit guess with the keyword guess=alter, I even find lower
 enery. Then it means Gaussian 98 can't give the ground state of
 La automatically? If so then how can I be sure the orbital order
 what I get correspond to the ground state?
 In addition I even found using the same input file, Gaussian 98
 for windows A3 and Gaussian 98 for linux A7 can give different
 results. Even the number of primitive basis functions are
 different. What goes wrong?
