We have TinyMCE 3.2.6 installed but we're still having problems with weird html comments being included when cutting and pasting from Word 2003 into Firefox.  Maybe my TinyMCE settings are wrong?  Here they are:

     theme: "advanced",
     mode: "textareas",
     editor_selector: "tinyMCE",
     content_css: "http://www.sussex.ac.uk/includes/css/standard.css",
     plugins: "paste",
     paste_auto_cleanup_on_paste: true,
     theme_advanced_toolbar_location: "top",
     theme_advanced_toolbar_align: "left",
     theme_advanced_buttons1: "bold,italic,underline,link,unlink,justifyleft,justifyfull,bullist,pasteword",
     theme_advanced_buttons2: "",
     theme_advanced_buttons3: ""

Suggestions welcomed!
