Initializing AJAX textareas freezes wrapper div's scrollbar

I have CKE initializing textareas that have been loaded via AJAX, in a colorbox modal window containing jQuery UI tabs panels.

Multiple textareas are dynamically loaded into a single scrollable container div, and then the initializing function runs to convert those into CK editors.

However, it seems that when I initialize CKE on these new textareas, it scrolls the container div down to one of the other textareas on the list, and though it initializes them correctly, you can no longer scroll the container div in Chrome. You can still scroll the container div in Firefox and IE, but not in Chrome. The scroll bar lights up when you mouseover, but neither the scrollwheel nor clicking and dragging the scrollbar will cause it to scroll.

It seems that if I initialize the text areas individually using a specific ID, the scrollbar does not freeze. However, when I initialize the textareas based on the class selector, as shown in the example below, it does.

Another weird behavior: If I click back and forth to select one of the editors and then select another, and if I do this a few times, it magically unlocks the scroll bar. Somehow, the act of switching the active editor a few times frees it up.

My AJAX call:

function getStuff(id){
        $.ajax({
            type: 'POST',
            url: '/ajax/get_stuff',
            data: {id: id},
            beforeSend:function(){  
                $('#panel').html('Loading...');                                 
            },
            success:function(resp){             
                $('#panel').html(resp); 
                ckInit();
            },
            error:function(){}
        }); 
    }

and the initialize function:

function ckInit(){
    var config = {              
             extraPlugins : 'autogrow',
             autoGrow_onStartup : true ,
             removePlugins : 'resize'               
        };
    $("textarea.ck").each(function() {              
        if (typeof(CKEDITOR.instances[this.id]) == 'undefined') {           
            CKEDITOR.replace(this.id, config);
        } else {
            CKEDITOR.instances[this.id].destroy(true);
            CKEDITOR.replace(this.id, config);
        }           
    });
}

Any help would be MAJORLY appreciated, if you need more information please let me know. Thanks in advance!
