Multi inner grid scroll bar problem

Hi Everyone,

I have just join a new development grup. Our group leader has already worked on the problem. However It look there is no easy way to solve problem. Here is the code:

<html> 
<head> 
   	<script src="../../runtime/lib/aw.js"></script>
    <link href="../../source/styles/xp/aw.css" rel="stylesheet"></link>
</head> 
<body> 
This example shows a grid inserted within a grid. It also illustrates how to expand a row when the plus is clicked. Note that the inserted grid (grid2) is used repeatedly so only 1 row can be expanded at a time. You also could replace grid2 with another AW object such as radio buttons or checkboxes. <b>There are a few bugs in the scrollbar code. The inserted grid seems to inherit scrollbar properties from the main grid.</b>

    <style> 
  
 #Mygrid { font: menu ; margin: 3px 3px 3px 3px;  }  
 #Mygrid .aw-item-text { vertical-align: top; }  
 #Mygrid .aw-alternate-even {    BACKGROUND: #f0fff0 } 
 #Mygrid .aw-alternate-odd { BACKGROUND: #ffffafa } 
 #Mygrid .aw-mouseover-row { BACKGROUND: #b0e0e6; } 
 #Mygrid .aw-rows-selected {    BACKGROUND: #008b8b } 
 #Mygrid .aw-column-0 {width: 20px; border-right: 1px dotted #ccc}

 #Mygrid2 {width: 100px;}
 #Mygrid2 .aw-column-0 {width: 100px; border-right: 1px dotted #ccc}
  
    </style> 

<script> 

        var myData = [ 
            ["+","2/1/2006", "Tom Smith", "Message 1"],

When we open multi inner grid scroll bar is not completely working right. Also we had to make refresh main grid in last section of onCellClicked. This seems not a good solution espacially if we had much more data.

Could anyone help me?

Thanks for advance..
