Still throwing a.grid.bdiv Error: 'a.grid.bDiv' is null or not an object on line 61

Still receiving an error after changing virtually everything I am able to think to change & still receive the error:

Line: 61   Error:  'a.grid.bDiv' is null or not an object

It throws this error in IE8.  I had previously posted this issue in this forum here.  

Here's what has been done:

Query that returns data has been optimized & returns data in around 50-70ms (it had been between 300-600ms, with some varying higher than that).

Removed the interval that was calling the code that created the grid every time.

Adding a second query to set a switch to only reload the grid when we have new or changed data in it.

Replaced the setInterval with a setTimeout that calls the second query that checks for new data (this executes every X seconds).

The code now performs the 2nd query (a count) every X seconds, and in the success portion of that AJAX call, if the count is > 0, then the code to unload the grid is called, followed by the code that calls the function to build the grid.  

The error is thrown from:  jquery.jqGrid.min.js on line 61

if(a.p.treeGrid===true)try{F.jqGrid("setTreeNode",G+1,l+G+1)}catch(S){}if(!a.p.treeGrid&&!a.p.scroll)a.grid.bDiv.scrollTop=0;a.p.reccount=l;a.p.treeANode=-1;a.p.userDataOnFooter&&F.jqGrid("footerData","set",a.p.userData,true);if(j){a.p.records=w;a.p.lastpage=Math.ceil(w/C)}g||a.updatepager(false,true);if(j)for(;l<w;){x=c[l];D=k(x,l+H);D=a.p.idPrefix+D;if(i.repeatitems){E||(E=U(s+u+m));var P=b.jgrid.getXmlData(x,i.cell,true);b.each(E,function(b){var c=P[this];if(!c)return false;o=c.textContent||c.text;

I'm not able to find this code elsewhere.  Using jqGrid 4.5.2 & jQuery 1.9.1.  Would appreciate any suggestions as to what's causing & how to resolve this error.
