Nivas,

 

We will investigate this issue and will get back to you as soon as possible.

 

Here is a work-around:

 

Add the following Initialize Script Code(force first editor gets focus) into the last editor (Editor9) on the page:

<script runat="server">
 override protected void OnInit(EventArgs e)
 {
     base.OnInit(e);  
     Editor9.AddInitializeScriptCode(" document.getElementById('"+Editor1.ClientID+"').FocusDocument()");
 }
 </script>
