mouseWheelEnabled 'Broken'

Is it just as simple as adding the bold line into my code to get the scrollwheel to work on the mouse for a text field? If so it aint working! :frowning:

function loadTxt(theTxt){
    var lv:LoadVars = new LoadVars();
    lv.onLoad = function(success:Boolean){
        if (success){
            my_text.html = true;
            my_text.htmlText = lv.txt;
		**my_text.mouseWheelEnabled = true;**
            trace ("cannot load text!");
