Unable to click through DIV to Tree Expanding Icon

[Sean]

Hi,

I have an issue with a maximised RadWindow.   I am programattically adding a RadWindow to the WindowManager described below.  

     <telerik:RadWindowManager ID="ucRadWindowManager" runat="server" RestrictionZoneID="divRadZone"
         KeepInScreenBounds="true">
         <Windows>
            <telerik:RadWindow ID="RadWindow1" runat="server">
            </telerik:RadWindow>
         </Windows>
      </telerik:RadWindowManager>

When I open the window, I am opening it maximised.  When the RadWindow opens, the parent window underneath adjusts itself and the width and height of the page both extend beyond 100%, which means that scroll bars appear on both axis. 
When using the built-in 'Close' in the corner of the RadWindow to close, the parent window adjusts itself and the scroll bars disappear.  However, when using a button in the RadWindow as a mean of closing, the readjustment of the parent window does not occur and you are left with scroll bars and part of the parent page has now extending beyond 100%.

This only occurs when the RadWindow is opened maximised.

I am closing the RadWindow using this code :

      function GetRadWindow() {
         var oWindow = null;
         oWindow = window.frameElement.radWindow;
         return oWindow;
      }

         GetRadWindow().close();

In an attempt to combat this issue I am trying to utilise a restriction zone for the RadWindow.

I have the DIV for the RestrictionZone set up as follows :

<div id="divRadZone" style="position: absolute; left: 0px; top: 40px; width: 800px; height:400px; z-index:0;">

This works fine, with one important and serious limitation.  The div appears over a RadTree, and the + symbols are not able to be clicked through the DIV.  The node names can be clicked, just not the '+' expanding icon.

As you can see, I have 2 issues here, a solution to either would be fantastic!
