Dynamic Menu not working with safari

Hello,

I'm stuck again with this dynamic menu in vwd2008, this time with safari. It does not show the menu. I have added this code

Code:

 
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
        'Safari Hack
        If Request.UserAgent.IndexOf("AppleWebKit") > 0 Then
            Request.Browser.Adapters.Clear()

        End If
        
    End Sub

to my masterpage. However, it doesn't work when the page loads the first time, but if you hit reload then the dynamic menu displays.
