It seems they are now supported by IE judging from this page http://www.startssl.com/?app=40 which show icons of all the major browsers incl. IE but excl. Opera, and this page http://www.startssl.com/?app=22 which has the following text redacted (overstrike): Startcom’s certificate isn’t trusted by the Microsoft Internet Explorer.
So I think that it is now supported by IE, question is, which version of IE and/or Windows. I can’t find any details about this on the StartSSL’s pages (there used to be a FAQ entry iirc with browsers supported which included version and OS).
