[jQuery] blur( fn ) doesn't work in Opera?

[jQuery] blur( fn ) doesn't work in Opera?


I am using this code:
    $(document).ready(function() {
        $('#inputthreadtitle').blur(function() {
            var value = this.value;
            $('td#similarthreadcheckcontent').html('<img src="images/misc/
13x13progress.gif" />');
         $.get("ajax.php",
         { do: 'getsimilarthreads', title: value },
         function(data){
            $('td#similarthreadcheckcontent').html(data);
         }
         );
        });
    });
with the latest release of jQuery but Opera doesn't react on the
onBlur event. When I write something to the input field and then click
somewhere, Opera just does nothing. :-(
