isClientSelectCheckBox is not defined

[MD]

I'm getting javascript errors ('isClientSelectCheckBox is not defined') every time when trying to select a single row.  I'm able to drag to select multiple rows, but when I try to select a single row I get the error.  I'm using an ASP.NET skin for most of the grid structure.  Any ideas?

Skin:

<telerik:RadGrid SkinID="RadGridSkinOne" runat="server" AllowMultiRowSelection="True" AllowMultiRowEdit="True"
        AllowPaging="True" AllowSorting="True" GridLines="Vertical">
    <MasterTableView AutoGenerateColumns="False" AllowMultiColumnSorting="True" PageSize="15" CommandItemDisplay="Top">
        <PagerStyle Mode="NextPrevNumericAndAdvanced" Position="TopAndBottom" />
    </MasterTableView>
    <ClientSettings EnableRowHoverStyle="true">
        <Selecting AllowRowSelect="true" EnableDragToSelectRows="true" />
        <Scrolling AllowScroll="false" />
    </ClientSettings>
    <ItemStyle HorizontalAlign="Left" />
    <HeaderStyle HorizontalAlign="Center" />
</telerik:RadGrid>

Grid:

<telerik:RadGrid ID="radgOne" SkinID="RadGridSkinOne" runat="server" Height="100%">
    <MasterTableView DataKeyNames="ID">
        <CommandItemTemplate>
                    <!-- Command Template Here -->
        </CommandItemTemplate>
        <Columns>
                    <!-- Columns Here -->
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

Looks like it was fixed in 2009.3.1503.20.
