Javascript error with xinha on IE if no www

If you are getting an error with xinha/tinyMCE in IE, something like this

Line 2182 Char 3 Error ‘null’ is null or not an object Code 0 URL http://irtpa.com/mods….

It can be fixed by making sure there the www (or subdomain) is present in the URL. Don’t know why this is so upsetting for xhina/ie…..
