genetic algorithm stopped working

 
... yeah, i have this strange thing happening - whether i have the "Genetic Algorithms" box during optimization checked or not it still trots all mud meticulously one by one iterating all inputs. anyone has any idea why?.. ever seen anything like that? . I think that i had it once, and re-installation of MT was the only thing that helped... but i i really hope i';m just missing something and it can be fixed somewhat easy.
