Change of icon

[PaLaMuNDeR]

Hi, I am trying to modify the icon for dragging, but my changes seem not to be affecting the outcome.

I have modified the sortable.css:

#result_list div.drag {
	background: url(../icons/arrows.png);
	cursor: pointer;
}
/* styles for tabular inlines */
div.inline-group table.ui-sortable tr.form-row.has_original td.drag {
	cursor: pointer;
	background-image: url(../icons/arrows.png);
}

But I still see the old view

Tried to restart the application, the server and so on, but no effect. The file is still loaded as before

If I try to modify the css straight from the browser, I can see the image, so it is loaded from the server.

Is it me that is missing something?
