Scroll bar missing in grid attached to layout

Hi,
I have a dhtmlxwindow and inside a layout (‘2U’). The left side part holds the grid which doesn’t show the scroll bar? How can I fix this?
Code:

...
        var layout = new dhtmlXLayoutObject("RoleRCsWndContainer", '2U');
        
        //Table
        var layoutLeft = layout.cells('a');
        layoutLeft.hideHeader();
        layoutLeft.setWidth('480');
        //layoutLeft.setHeight('170');
        layoutLeft.fixSize(1,1);
        
        RoleRCsGrid = layoutLeft.attachGrid();
       
        RoleRCsGrid.setHeader("A,B,C");
        RoleRCsGrid.setColTypes("ro,ro,ro");		
        RoleRCsGrid.setColSorting("str,str,str");
        RoleRCsGrid.setInitWidths("*,140,110");
        RoleRCsGrid.setSkin("xp");
        RoleRCsGrid.enableAlterCss("even", "uneven");
        RoleRCsGrid.init();
        var url = "./data_xml/role_rcs_xml.php?etc="+new Date().getTime()+"&role_id="+roleId;
        RoleRCsGrid.loadXML(url);

...

<div id="RoleRCsMainWndContainer"  style="width: 680px; height: 250px; line-height: 14px;">
    <div id="RoleRCsWndContainer" style="width: 680px; height: 220px; border-bottom: 1px solid #ddd; overflow: auto;"></div>
</div>    

Parent div’s style is set to ‘overflow: auto’ as you can see.

As you can see on image the bottom row can’t be seen (if you look closer, you can see only small dots and that is the top of the row) and no scroll bar to scroll down?
Thanks in advance

Hi
Locally everything is ok.
Could you provide completed demo with a link on this topic on support@dhtmlx.com ?
