Autoscroll div with jQuery to the bottom after appending

Question

I have a div class='messages'. I add date to this div via jQuery.append() Here are the styles:

.messages {
border: 1px solid #dddddd;
padding:10px;
height: 400px;
overflow-x:visible;
overflow-y: scroll;
-webkit-border-radius: 5px;
-moz-border-radius: 5px;
border-radius: 5px;
margin-bottom:10px;
font-size:14px;
}

For autoscroll I use such function:

receiveMessage = function (name, message, type) {
    //adding new message
    $("#messages").append('<strong>' + name + ": " + '</strong>' + message + '<br>');
    /autoscrolling to the bottom
    $("#messages").animate({
        scrollTop: $("#messages").height()
    }, 300);
}

About ~20 messages are scrolling normally, but after it 'hangs', new messages are not scrolled. Chrome Version 19.0.1084.56 . What I'm doing wrong? Thanks!

Please try:

$(document).ready(function(){
   $('#chat-scroll').animate({scrollTop: $('#chat-scroll')[0].scrollHeight}, 2000);
});
