Help with my news scroller!

Hey -
I have a news scroller which is working apart from one thing:
The end of the text string does not quite scroll completely off the screen - it disappears into thin air near the end and THEN starts scrolling from right to left again.
How do I make it so the text scrolls completely off the screen before returning?


var loadText:LoadVars = new LoadVars();
loadText.load("news.txt");
loadText.onData = function(src:String):Void  {
    if (src != undefined) {
        news_txt.htmlText = "																"+src;
        scrollText();
    } else {
        news_txt.htmlText = "could not load data";
    }
};
function scrollText() {
    onEnterFrame = function () {
        if (news_txt.hscroll<news_txt.maxhscroll) {
            news_txt.hscroll+=30;
        } else {
            news_txt.hscroll = 1;
        }
    };

}
