jquery ui draggable: gets jumpy when you click on the handler.

jquery ui draggable: gets jumpy when you click on the handler.

Did any come across this buggy thingy with jquery `draggable` before when you add `right: 0; bottom: 0;` to your popup box?

The box **jumps** away from your cursor when you **click on** the `handler`

jquery,

    $(".popup").draggable({ 
    cursor: "move",
    handle: ".popup-outer",
    cancel: ".popup-inner"
    });

html,

    <div class="popup-outer popup">
        <div class="popup-inner">
            <div class="box-close"><a href="#" class="button-close">x close</a></div>
            <div class="ajax-response"></div>
        </div>
    </div>

css,

    .popup-outer{
        position:absolute;
        
        top:0;
        left:0;
        right: 0; //this causes the bug
        bottom: 0; //this causes the bug
    
        max-width: 1000px;
        height:500px;
        margin: auto;
    
        padding:6px;
        -moz-border-radius:4px;
        -webkit-border-radius:4px;
        border-radius: 4px; 
        background: url(../image/trans_black.png);
    }
   
    .popup-inner {
        text-align:left; 
        background-color:#ffffff; 
        margin:0px; 
        padding:20px;
        overflow:hidden; 
        -moz-border-radius:2px;
        -webkit-border-radius:2px;
        border-radius: 2px;
        border:0px solid #999;
        color:#333333;
        
        border:0 solid red;
        
        cursor:default;
    }

any idea how can I fix it?
