[Flash CS3] Changable Font Size Dynamic Text and Scrolling!

Hello,

I’ve got a dynamic text box loading text. In the interface there are three buttons to increase or decrease font size. The text box has the usual Flash scrollbar component.

When you click on the large font size, you can still scroll, but eventually the text gets cut off.

Here’s some related code:


articleTextBox.html = true;
articleTextBox.multiline = true;

//htmltext is loaded into text box....

//buttons for changing font size
btnTextSize1.onPress = function() {
    myTextFormat = new TextFormat();
    myTextFormat.size = 12;
    articleTextBox.setTextFormat(myTextFormat);
}
btnTextSize2.onPress = function() {
    myTextFormat = new TextFormat();
    myTextFormat.size = 14;
    articleTextBox.setTextFormat(myTextFormat);
}
btnTextSize3.onPress = function() {
    myTextFormat = new TextFormat();
    myTextFormat.size = 18;
    articleTextBox.setTextFormat(myTextFormat);
}

Does any one know a trick to get the increase the font size without it getting cut off?
