Using Using RadControls 2008.3.1314, Internet Explorer 6, ASP.NET 2.0.50727.

I am experiencing an oddity with the Grid Header Context Menu in both my application and on the live demo page. The Grid loads and all columns are visible, but when I right click to access the header context menu, all the columns in the "Columns" context sub-menu have an unchecked state, as if there were not visible. However, as soon as I access the header context menu a second time, the checked states correctly match the actual visibility of the Grid's columns. Then, if I force the Grid to rerender (sort, group, ungroup, etc.), the context menu shows all unchecked again even though the columns are actually visible.

Setting Display="true" for any given GridBoundColumn has no effect on this behavior. Does anyone else experience this behavior on the demo page?

Here's how I'm defining my RadGrid:

    
            <telerik:RadGrid ID="RadGrid2" runat="server" DataSourceID="sdsFreTats" GridLines="None" 
        
                ShowGroupPanel="True" Skin="Office2007" AllowSorting="True" AutoGenerateColumns="False" 
        
                AllowPaging="True" PageSize="40" ShowFooter="True">  
        
                <ClientSettings AllowDragToGroup="True" AllowColumnsReorder="True" ReorderColumnsOnClient="True" 
        
                    AllowColumnHide="true">  
        
                    <Resizing AllowColumnResize="true" /> 
        
                    <Selecting AllowRowSelect="True" /> 
        
                    <Scrolling AllowScroll="True" UseStaticHeaders="True" /> 
        
                </ClientSettings> 
        
                <MasterTableView DataSourceID="sdsFreTats" GroupLoadMode="Client" TableLayout="Fixed" EnableHeaderContextMenu="true">  
        
                    <Columns> 
        
                     ...  
        
                    </Columns> 
        
                    <PagerStyle Mode="NextPrevAndNumeric" /> 
        
                </MasterTableView> 
        
                <HeaderContextMenu Skin="Office2007">  
        
                    <CollapseAnimation Duration="200" Type="OutQuint" /> 
        
                </HeaderContextMenu> 
        
                <FilterMenu Skin="Office2007">  
        
                    <CollapseAnimation Duration="200" Type="OutQuint" /> 
        
                </FilterMenu> 
        
                <PagerStyle Mode="NextPrevAndNumeric" /> 
        
            </telerik:RadGrid>

In the radgrid header context menu, while deselecting all the columns from the menu but we can not deselect the last column as it is read only. Is it possible to deselect the last column also?
