[AS2] How do you reset the scroll bar to the top in a TextArea field?

[alciabides]

I have buttons that when clicked dynamically populate the TextArea object w/scroll bar with text. When I click one and populate with text, if I scroll down and then click another button the text starts where the scroll bar left off.

Any help with resetting the scroll bars position to the top would be greatly appreciated. Thanks in advance. :o
