Problem with textarea

Hi to everyone's

I have a strange problem with CkEditor 3.x. Each time I want to add a textearea inside a Form generated with the editor, after saving it into the database and reopen-it, everythings below the textarea ar now located outside of the editor ? This only occur when I add a textarea.

Image 1 ( no textarea, everythings fine)


Image2 (after adding a textarea, save and reopen-it, the submit button his now outside the editor) ??


Anyone have an adea about that ??

Thanks !
