Problem with AJAX & Delegates.

Problem with AJAX & Delegates.

Hey!

I actually have the problem, which is discribed in the F.A.Q of JQuery - http://docs.jquery.com/Frequently_Asked_Questions#Why_do_my_events_stop_working_after_an_AJAX_request.3F

So I tried delagates. The problem now is, that the hover effect i wanted to create over a table, does only work every second time I click a link. That's rather strange.

What  am I doing wrong?

                            });
                           
                             $.ajax({
                                    type: "POST",

            <div class="content">
            <p id="text">testtest</p>

            </div>
        </div>
   </body>
</html>

My Css for that:
* { font-family: Georgia, Verdana; font-size: 10pt; color: gray; }
div.top {    position: relative; width: 50%; background-color: gray; color: white; margin: auto; padding: 1em 2em;}
div.content {   position: relative; width: 50%; margin: auto; background-color: #DDDDDD; padding: 1em 2em;}
div.naviontop {    position: relative; float:right;}
tr { border-left: solid white; }
a { text-decoration:none; color:white;}
a:hover {   color: white; padding-left: 3px; border-left: thick solid white; }
tr.hover {  background-color:#EEEEEE;}

It's all quite simple, but i can't understand why my planned effect works just every second time... :/

Thanks for your help in advance!
