The origin code is :

 

 <script>
  
 AdjustLayout();
 
 setInterval(AdjustLayout,100);
 
 function AdjustLayout()
 {
  if(document.all)
  {
   chat_layout.style.width=document.body.clientWidth-6+"px";
   chat_layout.style.height=document.body.clientHeight-6+"px";
  }
  else
  {
   chat_layout.style.width=window.innerWidth-6+"px";
   chat_layout.style.height=window.innerHeight-6+"px";
  }
 }
 function m_over(element) {
  element.className='buttonover';
 }
 function m_out(element) {
  element.className='button';
 }
 </script>

 

Please remain the m_over and the m_out.
