resize method working well in verion 7.2

It's a bug. For the height it's used correctly. Thus I copied the sourcecode and wrote my own function. For everyone having the same problem here it is:

function resizeGrid(grid, width, height)
{
   
    width = (width<0)?0:width
    height = (height<0)?0:height
   
   
    if(!ig_csom.IsIE || ((ig_csom.IsIE6 || ig_csom.IsIE7) && igtbl_isXHTML))
    {
        // need to set the width first so we can see whether anything (groupby box) is going to
        // get taller or shorter because of changes to text wrapping
       
        var marginWidth = igtbl_dom.dimensions.bordersWidth(grid.MainGrid);
        grid.MainGrid.style.width = width + "px";
        document.getElementById(grid.Id + "_mc").style.width = (width - marginWidth) + "px";
       
       
        grid.MainGrid.style.height = 0 + "px";
       
        // measure how much space all the fixed elements are going to need
       
        var marginHeight =  igtbl_dom.dimensions.bordersHeight(grid.MainGrid);
        for(var x=0; x<grid.MainGrid.rows.length; x++)
        {
            if(grid.MainGrid.rows[x].id != grid.Id + "_mr")
            {
                marginHeight += grid.MainGrid.rows[x].offsetHeight;
            }
        }
       
       
        if(height < marginHeight) {
            height = marginHeight;
        }
       
        // set the new widths and heights of the outer table and rows area
        grid.MainGrid.style.height = height + "px";
        document.getElementById(grid.Id + "_mr").style.height = (height - marginHeight) + "px";
        document.getElementById(grid.Id + "_mc").style.height = (height - marginHeight) + "px";
    } else {
        grid.MainGrid.style.width = width + "px";
        grid.MainGrid.style.height = height + "px";
    }

}
