Our Solution was to put the following code in Page_Init:

 

        Page.ClientScript.RegisterClientScriptInclude("CuteEditorConstant", "/CuteSoft_Client/CuteEditor/Scripts/Constant.js")
        Dim LoaderName As String
        Select Case Request.Browser.Browser
            Case "IE"
                LoaderName = "IE_Loader"
            Case "Firefox"
                LoaderName = "Gecko_Loader"
            Case "AppleMAC-Safari"  'Apple MAC Safari or Google Chrome
                LoaderName = "Safari_Loader"
            Case "Opera"
                LoaderName = "Opera_Loader"
            Case Else
                LoaderName = "IE_Loader"
        End Select
