jQuery Grid Plugin - jqGrid

Hello Guys,

I'm creating a simple jqGrid instance without any feature related to scroll enabled. 

Basically, if you access my web page, you will see a grid (jqgrid) and a link. When the user clicks the Link, a main DIV (containing my grid) in the web page will get replaced with another HTML data. 

My issue is that when the user clicks on the link while the grid it's still loading, meaning that it's still requesting the data and getting it from the Web Server, it fails. This is happening with both jqgrid v3.8.1 and jqgrid v4.1.1. 

When that happens, only in IE I'm receiving an error in:

• jqgrid v3.8.1: grid.base.js (line 1286) - "Microsoft JScript runtime error: Unspecified error".
• jqgrid v4.1.1: jquery.jqGrid.src.js (line 1327) - "Microsoft JScript runtime error: Unspecified error".

Both versions are pointing to the same code line:

if(!ts.p.treeGrid && !ts.p.scroll) {ts.grid.bDiv.scrollTop = 0;}

If I comment that line, in both versions work just great.

Is this a known bug?
