extjs gridfilter icon not showing in IE but shows in Firefox

In Gridfilters, if you are using a StringFilter field, then there is a property in StringFilter.js called :

icon: 'ux-gridfilter-text-icon',

Basically this loads a 'binocular' icon in beside the filter text box. This works fine with mozila, but with IE, the icon is not showing up.

Is this a known problem by any chance?

I am using the source at : http://ccinct.com/lab/filter-grid/

My ext js ver is 3.2.1

The girdfilters version seems to be v0.2.7 as per Gri开发者_开发知识库dFilters.js

EDIT: This works in Chrome fine. Just IE is the problem

EDIT#2: Also , the other css properties like column headers etc are fine. it is with the loading of the image that there is a problem.

Thanks. it got solved.
I had taken the filters plugin (ux,resources) folders, and distributed the files in diff packages in my web application.
For some reason, that messed up things even though the references were all correct. When I started using the package as it was given, it got solved.
Not sure why though.
