Spry menu bar 2 IE9 issue

Question

Hi,
I have a slight problem with a spry menu bar when viewed in IE9beta, when you hover over a menu item the hover background does not always complety fill the area immediately, eventualy it does.  This problem only affects IE9beta, I have tested it in the latest versions of safari, opera, firefox, and chrome.
Any help with this would be appreciated,
Richard.
You can view the menu at www.eandhbaxendale.com and I have included the css and widget script below
<script type="text/javascript">
// BeginOAWidget_Instance_2141544: #BaxMenuBar
var BaxMenuBar = new Spry.Widget.MenuBar2("#BaxMenuBar", {
      widgetID: "BaxMenuBar",
   widgetClass: "MenuBar  BaxMenuBarFixedLeft",
   insertMenuBarBreak: true,
      mainMenuShowDelay: 100,
      mainMenuHideDelay: 200,
      subMenuShowDelay: 200,
      subMenuHideDelay: 200
// EndOAWidget_Instance_2141544
</script>
/*menu bar start*/

I must have looked at it in another browser, sorry.
Had another look at it and indeed it may become an issue in IE9, but because IE9 is still in beta, anything can change.
Watch this space.
