function rolling() {

tmp.top = parseInt(tmp.top)-roll_speed;

if (parseInt(tmp.top) <= -roll_height) { tmp.top = roll_height*(total_area-1); }


if (s_tmp++ > (s_amount-1)*roll_text.length) {
====>추가 s_tmp=0;
wait_flag=false;
window.setTimeout("wait_flag=true;s_tmp=0;",waitingtime);

}
}
window.setTimeout("rolling()", 1);
}


30분 돌려도 딱 맞네요.
