FCKeditor 2.5 and BodyClass

Hi,

Is it even possible to define 'background-color' in the CSS file for my BodyClass? Font size, colors, padding etc. are working but setting background-color is not working.
I'm using FCKeditor with the following setup:

$oFCKeditor = new FCKeditor('content');
$oFCKeditor->BasePath = '/fckeditor/';
$oFCKeditor->Config['BaseHref'] = baseUrl;
$oFCKeditor->Config['UserFilesPath'] = filesUrl;
$oFCKeditor->Config['ToolbarLocation'] = 'Out:xToolbar' ;
$oFCKeditor->Config['EditorAreaCSS'] = 'stylesheet.css'
$oFCKeditor->Config['BodyClass'] = 'content';

Some sample css:

body {
   margin: 0px;
   padding: 0px;
   background: url("images/bodyBg.gif");
   font: 12px/14px Georgia, Tahoma, Arial, Verdana, Helvetica, sans-serif;
   color: #4d6590;
}

.content {
   width: 850px;
   padding: 0px 40px 0px 40px;
   background-color: #ffffff;
   float: left;
}
