RadMenu Items Shifted

[Steve]

I am building an ASP.NET website with various Telerik controls using .NET 3.5 and Telerik RadControls_for_ASP.NET_AJAX_2010_1_309_dev.msi.  When I expand the detail records for a row in a RadGrid, I am seeing some odd behavior with the RadMenu...in particular, the menu items shift to the right slightly:

Menus OK

Menus after viewing details in RadGrid

In my masterpage I have a RadMenu that is common to all pages:

                        <telerik:RadMenu ID="RadMenu1" runat="server" Skin="Office2007" Width="100%">
                            <Items>
                                <telerik:RadMenuItem runat="server" NavigateUrl="~/Default.aspx" Text="Home"
                                    ImageUrl="~/images/home.png">
                                </telerik:RadMenuItem>

                                <telerik:RadMenuItem runat="server"
                                    Text="CU Management">

I think I found the problem.  In my master page there are some styling overrides that apply padding.  The padding appears to get applied to my menu items when I display the detailed grid rows:

.RadMenu .rmLink
{
    padding: 0 0 0 25px;
    outline: 0;
    float: left;
}

and...

.RadMenu .rmHorizontal .rmText
{
    padding: 0 12px 1px 0;
}
