Same here: IE8 on XP, FF 3.5.7 on XP, FF 3.5.7 OSX and Safari 4.0.4 OSX<p>Edit: Ohhhhhh I get it now; you have to enter your search term, hit the search button, and then select which portal you want to search through.<p>I think the interaction needs some work, but I do like the paging between the search engines. I'm not sure if I would want to do that a lot, but it is kind of novel (to me at least).
