    I'm not sure if this is going to be easily recreatable or not, however this was easily done on our end.  Here is the XAML of where our RTB exists:
    <Grid>
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="675" />
                    </Grid.ColumnDefinitions>
                    <Grid.RowDefinitions>
                        <RowDefinition Height="150" />
                    </Grid.RowDefinitions>
     
                    <telerikDocumentsHtml:HtmlDataProvider x:Name="dataProviderOrderDisclaimerDescription"
                                                           RichTextBox="{Binding ElementName=rtb}"
                                                           Html="{Binding Description, Mode=TwoWay, NotifyOnValidationError=True, ValidatesOnExceptions=True}" />
                    <telerik:RadRichTextBox x:Name="rtb"
                                            AcceptsReturn="True"
                                            AcceptsTab="True"
                                            HorizontalScrollBarVisibility="Disabled"
                                            VerticalScrollBarVisibility="Visible"
                                            IsSelectionMiniToolBarEnabled="True"
                                            IsSpellCheckingEnabled="False"
                                            LayoutMode="Flow"
                                            Grid.Column="0"
                                            Grid.Row="0" />
                </Grid>


    1. Add a blank line at the end of the content and persist (ensuring the content goes beyond the visible area of the screen)
    2. Reopen the screen and edit some text by opening the context menu and changing its appearance to bold
    3. Using only the arrow keys from that position, scroll down to the very bottom of the content.
    4. Attempt to scroll back up using the arrow keys and the screen has hung.  At this point, the only thing that can be done is to kill the browser process.

    I noticed several times that it appears the scrolling does not scroll all the way to the very bottom. Much like the editor for these posts, it stays just above the very bottom.  I don't know if that is related or not, but what we noticed.

    I've sent you what I have as far as code.  The only other thing left really is the content and it is important to ensure the content scrolls off the visible area. 

    We are using 2011.1.419.1040 due to other issues.  Again, making sure there is a line break at the very end of the content is what the key is to producing this problem.  Oh well...

    Hello Michael Mstg,
    Sorry, but we still cannot reproduce the problem at our side. Could you please send us (attached to a support ticket) sample runnable project that reproduces the exception, specifying which browser and Silverlight version you are using?

    Please, excuse us for the inconvenience. Looking forward to your reply.

    Kind regards,

    It does turn out that the latest version, 2011.3.1116.1040 fixes the issue.
