I have a RadMenu on the top 30 pixels of my Page.
Under that, filling the rest of the page is an IFRAME. (The Menu populates the IFRAME).

This works perfectly across all browsers except IE9 and IE10 standards mode where there is a little glitch.
The 1st time you Mouse-over the Root Menu, the sub Menu is hidden.
If you mouse over a menu item a second time, the sub menu appears as expected.

I've broken down the code on my page as simply as I can, I databind the Menu in the code behind.

<!DOCTYPE html>
<html style="height:100%">
<body style="height:100%">
<form id="form1" runat="server">
  <telerik:radscriptmanager id="RadScriptManager1" runat="server" />
  <div style="position:fixed;width:100%;height:100%;">
    <div style="width:100%;height:30px;">
      <telerik:RadMenu ID="radMenu" Runat="server" Flow="Horizontal" Skin="Black" EnableViewState="false" EnableEmbeddedSkins="true">
    <iframe id="contentPane" name="contentPane" style="padding-top:30px;width:100%;height:100%;display: block;border:0;"></iframe>

IE9 and IE10 standards has another minor issue that may be related... 
Once you mouse over the root item a second time so that a SubMenu appears.
If there is a third menu level, the menu will only expand about 2 pixels, so you never see sub-sub menus items.
This issue isn't as important, since I can probably fix it via css, but I thought I would include it since it only happens in IE9/IE10 standards mode and therefore possibly related to the topic issue.

Thanks for any help you can give!

Hello Brad,

By using the code that you provided and after adding several MenuItems for testing purpose I was not able to get the behavior that you describe in IE9. You can refer to the video here that demonstrates what I get from my side. Can you please open a support ticket where you can attach a simplified runnable project that I can test locally and help you out?

Kind regards,
the Telerik team
