Unsolved Keep Focus of textbrowser on top?

[levoxtrip]

Hello, I'm appending a list of text to my textbrowser every .... frame. To the list I also append new Text. The newest text is always the first element in the list so I want that the focus of the textbrowser is always at the top. Because when the list get's to long the textbrowser starts focusing on the bottom. I hope it is clear what I mean.
Thanks in advace,
Leon
