Oh yeah, I forgot about textareas and possible select fields. Change the code to:
[html]<script>
jQuery(function($){
$("._full_width input, ._full_width textarea, ._full_width select").click(function(e){
e.preventDefault();
e.stopPropagation();
e.stopImmediatePropagation();
});
});
</script>[/html]
That should include everything.
