FCKeditor 2.4.3 not completly vissible in textfield

Hi,

I have a problem, when i will change a item, the editor is not complete showen, installed the latest module 2.4.3.
What musst i do to see the editor complete.
See http://www.svhuizen.nl/joomla/Editor.jpg to see what i try to mean, because my English is not so good.



Thanx in advance,

Grtz.
