AvRichTextBox\RichTextBox\RichTextBox_SelectionRect.cs(208,18,208,38): error CS1061: 'ListBoxItem' does not contain a definition for 'GetVisualDescendants' and no accessible extension method 'GetVisualDescendants' accepting a first argument of type 'ListBoxItem' could be found (are you missing a using directive or an assembly reference?)

latest nuget package (1.6.5) fixes the "out of bounds error" at RichTextBox_SelectionRect.cs line 42.

Thanks.
