RADWindow causes parent page controls to freeze

[mww]

I have a RADWindow that I activate from my codebehind like this

this.ucContactEdit1.PopulateControls();
            this.RadWindowManager1.Windows[3].VisibleTitlebar = false;
            this.RadWindowManager1.Windows[3].VisibleStatusbar = false;
            this.RadWindowManager1.Windows[3].Width = Unit.Pixel(430);
            this.RadWindowManager1.Windows[3].Height = Unit.Pixel(310);
            this.RadWindowManager1.Windows[3].OnClientClose = "closeRadWindow";
            this.RadWindowManager1.Windows[3].VisibleOnPageLoad = true;

this is the definition

<telerik:RadWindowManager runat="server" RestrictionZoneID="offsetElement" KeepInScreenBounds="True" Modal="True" Animation="Fade" ID="RadWindowManager1"
                        EnableShadow="false" ShowOnTopWhenMaximized="false" Width="425" Height="525" DestroyOnClose="True" Behavior="Default" InitialBehavior="None" OnClientClose="OnClientClose">
                        <Windows>


                            <telerik:RadWindow ID="RadWindowEditor" runat="server"  Width="430" Height="310" VisibleStatusbar="False" Modal="True" KeepInScreenBounds="True" Animation="Fade" >
                            <ContentTemplate>
                            <uc7:ucContactEdit ID="ucContactEdit1" runat="server" />
                            </ContentTemplate>
                            </telerik:RadWindow>
                        </Windows>
    </telerik:RadWindowManager>

When I close the RADWindow the RADCombo boxes on  the parent window all freeze ! they can no longer receive focus (so the dont activate the drop down)

Im using Firefox 3.6.15 and Telerik Q1 2010

can anyone help ?

Hi,

Are you able to replicate the reported problem using the latest available Q1 2011 version 2011.1 315 of RadControls for ASP.NET AJAX? If the problem is fixed my recommendation is to upgrade to the latest build because the controls are optimized, improved and many bugs are fixed between Q1 2010 and Q1 2011.

If the problem still happens after the upgrade, please isolate it in a sample working project and send it for examination on our end by opening a new support ticket.

Best regards,
Rumen
