Bug: Repainting grid on scroll issue

Version: 2-0-b2
OS: Windows XP SP2
Browser: IE6

When I scroll the grid either by scroll mouse of scroll bar, rows are displaying as empty then loading a second later. This re-occurs everytime I make a reasonable scroll up or down the grid.

Below is a link to a screenshot.

This is a known issue? Is there anything that can be done to fix this?

Object Code:

var obj = new AW.Grid.Extended;
    obj.setId("myGrid");
    obj.setCellEditable(false);
    obj.setFixedLeft(0);
    obj.setSelectorVisible(true);
 	obj.setSelectorWidth(25);
    obj.setSelectorText(function(i){return this.getRowPosition(i)+1});
    obj.setCellText(myData);
    obj.setHeaderText(myColumns);
    obj.setFooterText(myFooter, 1);
    obj.setFooterVisible(true);
    obj.setFooterHeight(20, 0);
    obj.setFooterCount(2);
    obj.setFooterText(myFooter, 2);
    obj.setColumnCount(5);
    obj.setRowCount(100);
    document.write(obj);

This grid is amazing, congrats for a job well done.

Virtual Mode helps with a high volume of data. It's set to true by default.

obj.setVirtualMode(false);
