Frozen Column not displayed correctly in IE8

[tp6qw]

Hi~

Did anyone ever test Frozen Columns on IE8?
it seems the separater of Forzen Column (usually last one) would cover other columns which are after the forzen column.

Did anyone know how to fix this?

I grap the picture from here, the red regoin is what I said. Thx.

               or

                onComplete:function(grid){
                if($.browser.msie && $.browser.version=='8.0'){ $("#myGrid1_freeze_bodyDiv").css("left","-14px");}
                }
