1. Default cursor for iframe body is "pointer" instead of "default" or "text".
2. Safari uses an incorrect URL for EditorWysiwygModeCss property, when I set the URL to:
$editor->EditorWysiwygModeCss= "CuteEditor_Files/Style/content.css";
Safari will load:
/CuteEditor_Files/CureEditor_Files/Style/context.css
