Forums → Programming Forum → Flash MX 2004: Lag problem. Help plese

I recently strated creating a RPG game in Flash MX 2004 AS2.0 and when I start my game after 3-5min it starts lagging. Any tips? thanx code:
//_root
function rollover(who2, text2) {
timer = 1;
countdown = function () {
timer--;
if (timer == 0) {
textbox.text = "";
clearInterval(countdownInterval);
}
};
countdownInterval = setInterval(countdown, 1000);
if (_root.cursor.hitTest(who2)) {
textbox.text = text2;
}
}
function visible(who) {
if (who._x&gtlayer._x+300 || who._x&ltlayer&gtlayer._y+300 || who._y&ltlayer>
who._visible = false;
} else {
who._visible = true;
}
}
