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>
