I've implemented the DNNMenu on my website and I have it displaying horizontally using ul's. Which is nice, I have it all displaying exactly the way I want it to. However when it loads up I notice that the whole menu is displayed without any styling down the left side of the window. I can't figure out how to have it just display as normal right off the bat. Any one else having these issues or is there something that I am probably doing wrong?

I can only assume that I have done something wrong in my implementation. So take a look at my code and tell me if I've done something stupid.

<%@ Register TagPrefix="dnn" Namespace="DotNetNuke.UI.Skins" Assembly="DotNetNuke" %>
<dnn:NAV runat="server" id="dnnNav" IndicateChildren="true" providername="DNNMenuNavigationProvider" controlOrientation="horizontal" cssControl="menuControl">
                            <CustomAttributes>
                                <dnn:CustomAttribute Name="RenderMode" Value="UnorderedList" />
                                <dnn:CustomAttribute Name="MouseInDelay" Value="0" />
                                <dnn:CustomAttribute Name="MouseOutDelay" Value="0" />
                                <dnn:CustomAttribute Name="PopulateNodesFromClient" Value="true" />
                            </CustomAttributes>
                        </dnn:NAV>

It's showing up on the left side for a few seconds before it shows up horizontally with the styles that I set for it. of course this does not work well for usability or professionalism so please someone help.
