Solution 1:

whats is not working in your code

$(".mes").click(function(){
    var user = $(this).attr("id");
    $("#convo").html("<b>"+user+"</b>");
    $("#convo_ctrl").show();
    $(".send_to").attr("id",user);
    $(".convo_mes").html("Loading conversation <img width='15' height='15' src='./img/load.gif'>");
    setTimeout(function(){auto_scrollmes},3000);
    setTimeout(function(){get_convo(user)},2000);
});

    var objDiv = $("#convo_mes");
    objDiv.scrollTop = objDiv.scrollHeight;
