Scrollbar Component - At Start Point

1

Hi All,

please, I have a dynamic text field, that loads a external text.
There is a scrollbar component on it.

I have three buttons, when I click at one, it loads a new text at this text field.

Till there, everything is okay.

But, for example, my first text is there. then I scroll till the end of it. And when a load the second text. The scroll bar stays at the point i leave it.
And i would like to it comes to the star position.

please here is my code:


stop();
// 
System.useCodepage = true;
import mx.controls.*;
//
loadText = new LoadVars();
loadText.load("faq.txt");
//
loadText.onLoad = function() {
	scroller.text = this.faqintro;
};
// 
question1_btn.onPress = function() {
	loadText = new LoadVars();
	loadText.load("faq.txt");
	loadText.onLoad = function() {
		scroller.text = this.pergunta1;
	};
	myScrollBar.scrollPosition = 0;
};
question2_btn.onPress = function() {
	loadText = new LoadVars();
	loadText.load("faq.txt");
	loadText.onLoad = function() {
		scroller.text = this.pergunta2;
	};
	myScrollBar.scrollPosition = 0;
};
question3_btn.onPress = function() {
	loadText = new LoadVars();
	loadText.load("faq.txt");
	loadText.onLoad = function() {
		scroller.text = this.pergunta3;
	};
	myScrollBar.scrollPosition = 0;
};

Could someone be so kind, and help on this.

Thank you very much
