Set TextField horizontal scroll to initial position

If you want to set the position of horizontal scroll position inside TextField, you can use TextField.scrollH.

Let's say I am typing in the input TextField and I typed beyond the width of TextField. You will see the last characters visible you typed. Now due to some other event, say user clicks on other than this TextField, focus is changed to some other object than this TextField, you may want to reset the scroll position of TextField to starting characters in it.
You will use :
TextField.scrollH = 0;

This will set the horizontal scroll of TextField to 0 and hence showing the starting characters in TextField.

Default ContextMenu Items on Flash TextField

Is there any way to hide default context menu items on Flash TextField? Some one will try to answer with ContextMenu.hideBuiltInItems() function, but this function does not really work with Flash TextField. It does not hide the built in items.

So following code does work but not as expected ::

var myContextMenu:ContextMenu = new ContextMenu();
myContextMenu.hideBuiltInItems();

var txt:TextField = new TextField();
txt.contextMenu = myContextMenu;
addChild(txt);

Now if you right click on TextField then you will see that you can see all the built in item. Any one knows why?
