Publisher 2003 is designed to exploit the rich features of IE 6 and 7 that
include VML and PNG, as well as push the new standard of CSS2
(http://www.w3c.org). Looking at your sites it looks to me that Opera isn't
handling the CSS2 well. But you might check a couple of options and try
again. Under Tools menu, web options there are VML and PNG options, uncheck
both the rely on VML and the allow PNG settings and then resave and
republish. And see if that helps any. That is all you can modify in Publisher
2003.
