hello,

I have a long textfield with the UIScrollbar working perfectly, but I need to activate the mouse wheel support, however I´m doing something wrong because when I do it the whole text moves up and down but it doesn´t scroll, any idea what I´m doing wroong?

Thanks people.

[AS]mouseListener = new Object();  
mouseListener.onMouseWheel = function(delta) {  
nuestrafirma.\_y += delta;  
}  
Mouse.addListener(mouseListener);[/AS]

“nuestrafirma” is the textfield instance name.
