Crash in Telerik editor

[ASF]

Hello, browser crashes when I have selected a text  in the header or footer and then switch to main document body by doubleclicking to its area. This doesn't happen on demos though. There's something wrong with the SelectionMiniToolBar.
This is the stack trace:

MS.Internal.WrappedException: Error HRESULT E_FAIL has been returned from a call to a COM component.

 Could you please address the issue?

This happens if put RichTextBox in ChildWindow (or RadWindow). That's why it doesn't happen on demos.

Hi,

Thank you for writing.

This is a known issue for us and we have it in our product backlog. Unfortunately, at this time we cannot specify when it would be fixed. However, as a workaround you could disable the SelectionMiniToolBar when editing Header/Footer using the following code:

void rtb_ActiveDocumentEditorChanged(object sender, Telerik.Windows.Documents.UI.ActiveDocumentEditorChangedEventArgs e)
{
    if (e.DocumentEditorType == Telerik.Windows.Documents.UI.DocumentEditorType.MainDocument)
    {
        this.editor.IsSelectionMiniToolBarEnabled = true;
    }
    else
    {
        this.editor.IsSelectionMiniToolBarEnabled = false;
    }
}

I hope this is helpful. Please, do not hesitate to get back to us if you have additional comments or questions.

Regards,
Vasil

Yes, this is exactly the same workaround I did.
Thanks.
