jQuery Grid Plugin - jqGrid

Hi,

There is a problem selecting rows in the situation showed in below sample code.
When you select a sigle row, and then you select another row, both rows stay selected.
I noticed that if I remove the backslash (the same thing happens with slashes) from the username, selection works perfectly.

Thanks.

jQuery().ready(function() {
    // We use a document ready jquery function.
    jQuery("#list2").jqGrid({
    datastr: "{\\"Page\\":1,\\"Total\\":1,\\"Records\\":3,\\"Rows\\":[{\\"Username\\":\\"ISTRA\\\\\\\\marko\\"},{\\"Username\\":\\"ISTRA\\\\\\\\marko2\\"},{\\"Username\\":\\"ISTRA\\\\\\\\marko3\\"}]}",
    datatype: "jsonstring",
    jsonReader: {
        root: "Rows",
        page: "Page",
        total: "Total",
        records: "Records",
        repeatitems: false,
        id: "0"
    },
    height: 250,
        colModel: [
           { name: 'Username', key: true, label: 'Username', width: 150, editable: true },
           { name: 'DatabaseName', label: 'DatabaseName', width: 50, editable: false },
           { name: 'ServerName', label: 'ServerName', width: 50, editable: false },
           { name: 'ConnectionString', label: 'ConnectionString', width: 250, editable: true },
           { name: 'XslFilesPath', label: 'XslFilesPath', width: 250, editable: true }
         ],
        caption: "Manipulating Array Data"
    });
});
