ExtJS 4.0.0 web accessibilty issue in High Contrast mode.

Hi,

We are using ExtJS 4.0.0 in our application. All the background images of extjs does not show up when the application is accessed in High Contrast Mode. For ex: the ext-all.css has trigger.gif as background image and it does not show up in High contrast mode :

.x-form-trigger {
background-image: url("../../resources/themes/images/default/form/trigger.gif");
background-position: 0 0;
border-bottom: 1px solid #B5B8C8;
cursor: pointer;
float: left;
height: 21px;
width: 17px;


}

Kindly let me know how can we make these background images visible in High Contrast mode also?

You will likely have to create your own images then.

Is it there any possible solution with some css changes in ext-all.css.?
