Actually some scripts when saved can be very complex , guess it has to do on a average saving option it might get in conflict with a save that is parented and should not get that info in the script , as if you would save a figure this way and load it for another figure set then it would jump on a wrong spot :) at the beginning of Poser we were working mostly with script editing as it works pretty fast this way , sometimes might be even the better option as to figure out where the option might be in the applications.
