This code doesn't change anything...
SetCurrentAuthor("test", System.Windows.Media.Colors.Purple)
Public Sub SetCurrentAuthor(ByVal authorName As String, ByVal color As System.Windows.Media.Color)
RadRichTextBox1.CurrentUser = New Model.UserInfo(authorName, authorName, authorName, String.Empty)
RadRichTextBox1.TrackChangesOptions.CurrentAuthorColor = color
End Sub
I have an older version, so maybe I just need the update?
