I have a textbox defined as a multiline which is serving as a log. So, every seconds, a new line is added to the line. After a while, the content of the textbox will reach the bottom so the scrollbar will start to appear. But, the visual content is always on the first part of the text only. Even if I do this:

        Log.SelectionStart = Log.Text.Length

The cursor gets at the end but the visual content is always from the start. I can see also that the scrollbar moves back to the top. How can I achieve that?
