jQuery Grid Plugin - jqGrid

Hi,

I've developed the following grid using Firefox for testing, but when I've tryed to run the same grid in IE, it didnt work as it did in FF. Here's the code, hope you guys can help me!

jQuery("#listRac").jqGrid({      
        url:'index.php?m='+module+'&s='+submodule+'&action=listJson&nd='+new Date().getTime(),      
        datatype: "json",
        width: largura,       
        colNames:['','', 'Código', 'Registro','Título','Classificação','Responsável Dígitro',''],       
        height:220,
        colModel:[
            {name:'edit',index:'', width:'20',sortable:false},
            {name:'idSituacao',index:'ID_SITUACAO', width:'20', align:'center'},
            {name:'codigo',index:'CODIGO', width:'40', align:'left'},
            {name:'dtEmissao',index:'DT_EMISSAO', width:'60', align:'left'},
            {name:'DE_TITULO',index:'DE_TITULO', width:'200', align:'left'},
            {name:'cdClassificacao',index:'CD_CLASSIFICACAO', width:'80', align:'left'},
            {name:'nmResponsavelDigitro',index:'CD_FUNCIONARIO', width:'80', align:'left'},

            {name:'msg',hidden:true}
        ],       
        pager: jQuery('#pagerRac'),      
        rowNum:10,       
        imgpath: webjs+"/jquery/plugins/jqGrid/themes/digitro/images",       
        sortname: 'CODIGO',      
        viewrecords: true,      
        sortorder: "desc",
        multiselect: true,
        subGrid : true,
        subgridtype: 'json',
        subGridUrl: 'index.php?m=racWeb&s=rac&action=buscaHistorico&nd='+new Date().getTime(),
        subGridModel: [{
            name : [' '],
            width : ['*']
         }],         
        

        loadError : function(xhr,st,err) {
            jQuery("#displayMessages").html(xhr.responseText);
        },
  
        loadBeforeSend : function() {
            $('#emptyGridRac').css('display','none');
        },

        loadComplete : function() {
            atualizaGrid();
        
            ids = $("#listRac").getDataIDs();
            ret = $("#listRac").getRowData(ids[0]);
   
            totalReg = $("#listRac").getGridParam('records');

            if (totalReg == null) {
                $("#emptyGridRac").html('<span style="color:red">Não foi encontrado registros para a consulta</span>');
                $('#sp_2', $('#ctpg', $('#pagerRac'))).html('0');
                $('.grid_htable').css('display','none');
                $('#botaoEdit').css('display','none');
                $('#emptyGridRac').css('display','');
            } else {
                $('.grid_htable').css('display','');
                $('#botaoEdit').css('display','');
                $('#emptyGridRac').css('display','none');
            }

            if (ret.msg !=""){
                $("#displayMessages").html(ret.msg);
            }
        }

    }).navGrid('#pagerRac',{edit:false,add:false,del:false,search:false, position:'left'});

P.S – There are no javascript errors in IE and don´t bother worring about the variables that I use to assemble the URL's, width and etc cause they are correct (double checked it) 😉
