sortable list breaks TinyMCE

sortable list breaks TinyMCE

Hey,
i am using the jquery code:

  $("#blocklist").sortable({ 
    handle : '.handle', 
    update : function () { 

    } 
  });  
to make my <li> elements sortable..
works fine, except they have <textarea>s inside of them...
i have used the basic (non jquery) tinyMCE initialisation on every textarea,
...

when i sort the elements.. the very one i DRAG makes it's child textareas uneditable..
is there a way to refresh the tinyMCE? or what is the best solution?

many thanks for your time.
