News Crawler Flicker's

Hi Everyone,

I am trying to create a news crawler or ticker using Adobe Flash CS 5 (AS 3.0) but I notice that what I did is

not scrolling smoothly (the text actually flickers). Please see my source code below:

var endOfText= textCrawler._txt.x - (textCrawler._txt.textWidth + 50);

function scroller()
{
textCrawler._txt.width = textCrawler._txt.textWidth;
textCrawler._txt.multiline = false;
textCrawler._txt.autoSize = "right";

addEventListener(Event.ENTER_FRAME, onEnterFrame);
}
scroller();  //calls the function

function onEnterFrame(event:Event):void {
textCrawler._txt.x -= 4;
if (textCrawler._txt.x < endOfText)
{
var resetPos:Number = (textCrawler._txt.x * -1) + 2;

textCrawler._txt.x = resetPos;

this.removeEventListener(Event.ENTER_FRAME, onEnterFrame);
scroller();
}

}


Thanks for your time and help.
