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! 
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;**
}else{
trace ("cannot load text!");
}
};
lv.load(theTxt);
}
