AFAIK its mainly due to artithmic overflow as in too big numbers. I dont
have such big harddiscs in my system nor do I have RO 4+ (or docs)... so if
someone could give me either enough info or take up the job of updating it
(its a small small straitforward program really) I would be most gratefull.
