Hi,
is it safe to use the RichTextBox target? If new text is always appended without clearing its contents, the main memory is going to explode sooner or later...
The RichTextBox target unfortunately doesn't scroll up when new text is added. You have to add
rtbx.Focus();
rtbx.SelectionStart = rtbx.Text.Length;
rtbx.ScrollToCaret();
at the end of the method RichTextBoxTarget.SendTheMessageToRichTextBox
