Wysiwyg In Popup

Hi,

I am using the following code to create a dialog box:

      
        {include file="common/popupbox.tpl"
        id="edit-kb-question-{$product_question->question_id}"
        act="edit"
        link_text=$product_question->question
        href="bfa_knowledgebase.edit.question&question_id={$product_question->question_id}"}
      

Which works fine. The content of my popup, contains the following WYSIWYG textarea:

        {$question->answer}

Which again, works fine.

However if close the dialog and reopen it, it regenerates the wysiwyg field and I end up with 2 redactor inputs on my dialog. Close it again and reopen it and I have 3 redactor inputs. Etc. Etc.

Any ideas on how to stop this from happening?

Thanks..
