Problems with multipe instances

Hi,

i got a page with a various number of instances.

every Instance got a dynamic name and data like this:

            $data["ckeditor_".$ID[$i]] = array(
                //ID of the textarea that will be replaced
                'id'     =>     $ID[$i],
                'path'    =>    'js/ckeditor',
                //Optionnal values
                'config' => array(
                    //'toolbar'     =>     "Full",     //Using the Full toolbar
                    'toolbar'     =>     "Basic",       //Using the Full toolbar
                    'width'     =>     "550px",         //Setting a custom width
                    'height'     =>    '200px',         //Setting a custom height
                    'EnterMode' => 'CKEDITOR.ENTER_BR', // BR statt P
    
                )
            );

The view initializes the textareas with the proper IDs and at the end, I just display the ckeditor by using:

                $var_name = "ckeditor_".$ID[$i];
                echo display_ckeditor($$var_name); 

The problem I got now is, that there are not allways all instances displayed. By pressing reload or "F5" in my browser (FF 3.6), sometimes one or more CKEditor-Windows disapprear.

Any Ideas?

thank you!

Edit: Problem seems to appear only with FF
