EditorAreaCSS not working.

I am having no luck setting the EditorAreaCSS property. I have searched through a large number of forum posts and not found anything that has worked.

I have set up FCK editor on my local machine, within a fckeditor folder. To load the CSS I have used:

$sBasePath = '/fckeditor/';
$oFCKeditor = new FCKeditor('FCKeditor1') ;
$oFCKeditor->BasePath = $sBasePath ;
$oFCKeditor->Config['EditorAreaCSS'] = 'ucr_style.css'; // file exists in /fckeditor/
$oFCKeditor->Create();
