When I try to close the RadWindow on mobile (Chrome Mobile, Chrome Mobile desktop emulator) by clicking on the default Close button (aka X button), if I have a clickable element behind the X button, this one also grabs the input and triggers the OnClick event of the behind element.

The problem can be reproduced in the following demo http://demos.telerik.com/aspnet-ajax/window/examples/radopen/defaultcs.aspx.

Workaround:
<script>   
        function OnClientShow(sender, args) {
            $telerik.$(".rwCloseButton").bind("touchstart", function (e) {
                $telerik.cancelRawEvent(e);
            });
       }
</script>
<telerik:RadWindow OnClientBeforeShow="OnClientShow" RenderMode="Lightweight" ID="RadWindow1" runat="server" ShowContentDuringLoad="false" Width="400px"
                Height="400px" Title="Telerik RadWindow" Behaviors="Default">
</telerik:RadWindow>
