jQuery Grid Plugin - jqGrid

Hey guys, I'm having this wierd problem with the multisearch. Once I perform the search with some filters and the grid is reloaded with the results, the popup is still showing disabling the whole grid.

I search the forums and found this thread http://www.trirand.com/blog/?p.....38;ret=all with the same problem I'm having now. I've checked and I have the the css for the SearchFilter set (i'v downloaded a new zip from the site with all the modules) and change my includes and links accordingly.

I don't know what else it could be.

Here's the grid initialization:

$(document).ready(function() {
            var grid = $("#listCampaigns").jqGrid({
                url: '/MSCBA/Campaign/GetAll/',
                datatype: 'json',
                mtype: 'GET',
                colNames: ['Id', 'Title', 'Actions'],
                colModel: [
                  { name: 'Id', index: 'Id', width: 40, align: 'left', searchoptions: { sopt: ['eq', 'ne', 'lt', 'le', 'gt', 'ge']} },
                  { name: 'Title', index: 'Name', width: 400, align: 'left', searchoptions: { sopt: ['bw', 'bn', 'ew', 'en', 'cn', 'nc']} },
                  { name: 'Actions', index: 'Actions', width: 60, align: 'left', sortable: false, search: false}],
                pager: '#pager',
                rowNum: 10,
                rowList: [5, 10, 20, 50],
                sortname: 'Id',
                sortorder: "asc",
                viewrecords: true,
                forceFit: true,
                autowidth: true,
                height: '100%',
                caption: 'Campaigns'
            }).navGrid('#pager',
                            {
                                edit: false, add: false, del: false, search: true, refresh: true
                            },
                            {}, // edit options
                            {}, // add options
                            {}, //del options
                            {multipleSearch: true} // search options
                        );           
        });

The version of jqGrid i'm using is 3.5.3

Where did i go wrong with this one? any help is appreciated.

Thanks in advance.
