Fckeditor not appearing in IE6+

Hi,

I originally had a problem similar to http://drupal.org/node/239919
I updated the fckeditor module and fckeditor to the latest version and now all I get is just the normal text area in IE6,7 & 8. No editor toolbar and no JS errors popping up also. I've already tried clearing the browser cache and reverting back the fckeditor version.

It works fine on FF, Safari and chrome

Thanks.
