    My combo Box is crashing in this rather rudimentry setup. I've tried both of the following individually

                            <telerikInput:RadComboBox Grid.Column="1" Grid.Row="0" IsReadOnly="True" IsEditable="True" OpenDropDownOnFocus="True"
                                <telerikInput:RadComboBoxItem Content="Alex"/> 
                                <telerikInput:RadComboBoxItem Content="Albert"/> 
                            <telerikInput:RadComboBox Grid.Column="1" Grid.Row="1"
                                <telerikInput:RadComboBoxItem > 
                                    <TextBlock Text="Bert" /> 
                                <telerikInput:RadComboBoxItem > 
                                    <TextBlock Text="Bob" /> 

    When ever you open the combo box, it crashes (goes to white screen)
    However, if there is no content, I can open it fine (albiet, with an empty list of comboboxitems)

    (If it helps, I have a stackpannel layout root, then a canvas, then the grid, then the above code)

    Hi Alexander,

    There are two known possible reasons for the crash you are experiencing:
    1) Your Silverlight 4 runtime is not RTM (version less than 4.0.50401) and you are using the latest Silverlight 4 assemblies.
    2) You are using Telerik Silverlight 3 assemblies in a Silverlight 4 application.

    In the first case you need to upgrade the Silverlight 4 Tools to the latest available version on To resolve the second problem you need to download and install the Silverlight 4 version of our assemblies.

    Sincerely yours,
