    This exception occurred while I was using the RadRichTextBox, and it crashed my application.  I have not been able to reproduce it since.  I am on RadControls for WPF version 2012.3.1017.40.

    ShellApplication.HandleException : InteractionDesktopClient: App Domain Unhandled exception
    Top Exception
    Type=System.ArgumentNullException
    Source=mscorlib
    Message=Value cannot be null.
    StackTrace:
       at System.Threading.Monitor.ReliableEnter(Object obj, Boolean& lockTaken)
       at System.Threading.Monitor.Enter(Object obj, Boolean& lockTaken)
       at Telerik.Windows.Documents.DocumentPosition.Dispose() in c:\TB\105\WPF_Scrum\Release_WPF\Sources\Development\Documents\Core\DocumentPosition\DocumentPosition.cs:line 2626
       at Telerik.Windows.Documents.DocumentPosition.Finalize() in c:\TB\105\WPF_Scrum\Release_WPF\Sources\Development\Documents\Core\DocumentPosition\DocumentPosition.cs:line 2650

    Is this a known issue?

    Thanks,
