loadonce: true, // to enable sorting on client side

sortable:true //to enable sorting

When i try to sort IE is showing the Stop Running Script dialog saying "A script on this page is causing your web browser to run slowly. If it continues to run,   your computer might become unresponsive.".

I am using latest version of Jqgrid files. jquery-1.5.2.min.js, jquery.jqGrid.src.js, jquery.jqGrid.min.js.

What should I do to resolve this issue. Please help
