I can't position to a specific page of jqgrid

I am using a jqgrid but am having trouble positioning to a specific page. I have seen a couple of examples using reloadGrid which I have tried but it doesn't work. I have a large data set that is paged. If I try to go to page 76 of my data set it acts like it is trying to do it as the "View" count at the bottom is correct however the grid is displayed empty (even though my JSON data looks correct). I notice the scroll bar is still positioned to the top and if I touch it it automatically reloads back to page 1. Am I missing something?

Here is my grid definition:

$("#list1").jqGrid({
  url: 'jqgrid.php?cmd=getrecs',
  editurl: 'jqgrid.php?cmd=editrec',
  datatype: 'json',
  colNames:['Branch', 'Description', 'Type', 'Active' ],
  colModel :[
    {name:'rbranch',
            index:'rbranch',
            sortable:true,
            editable:true
    },
    {name:'des',
            index:'des',
            sortable:true,
            editable:true
    },
    {name:'type',
            index:'type',
            sortable:true,
            editable:true
    },
    {name:'status',
            index:'status',
            sortable:false,
            editable:true
    }
  ],
  pager: '#pager1',
  sortname: 'rbranch',
  sortorder: 'asc',
  rowNum: 100, // Only fetch 100 at a time
  viewrecords: true,
  scroll: 1,
  sortable: true,
  caption: 'Scheduling Resources'
});

$("#list1).navGrid("#pager1",
  // Turn on the icons
  {edit:true,
          add:true,
          del:true,
          search:true,
          refresh:true,
          refreshstate:'current',
          view:true
  },
  // Edit dialog parameters
  {reloadAfterSubmit: false,
          closeAfterEdit: true
  },
  // Add dialog parameters
  {reloadAfterSubmit: true,
          closeAfterAdd: true
  },
  // Delete dialog parameters
  {reloadAfterSubmit: false},
  // Search dialog parameters
  {},
  // View dialog parameters
  {}
);

To go to page 76 I am trying this:

$("#list1").trigger("reloadGrid",[{page:76}]);

You use scroll: 1 option. It's a special virtual scrolling mode. In the mode many things work in another way or not works at all. You can try to remove the option and use standard paging.
