Hi there. I reported this earlier as well, along with a script error from IE8. In version 2.3.4.5, Joe's log says he fixed the script error by blocking the Google search from appearing to IE users ("Fixed a bug where the google 404 enhancement gives a script error in IE, it is now disabled in IE"), but it really didn't address the core issue of the search itself not working in any browser. I would actually prefer to have the internal site search appear there (whichever site search method is selected in setup).
