Hi

Create Silverlight application with following xaml:

<UserControl x:Class="SilverlightApplication4.MainPage"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

mc:Ignorable="d"

d:DesignHeight="300" d:DesignWidth="400">

<Grid x:Name="LayoutRoot" Background="White">

<StackPanel>

<telerik:RadComboBox></telerik:RadComboBox>

<RichTextBox IsReadOnly="True">

<Paragraph>

<Hyperlink NavigateUri="http://www.google.com">

Silverlight</Hyperlink>

</Paragraph>

</RichTextBox>

</StackPanel>

</Grid>

</UserControl>

Scenario:
1. Click on ComboBox
2. Click on Hyperlink
Result: Silverlight crashed with exception:
