This is because the UT shows its pages in a frame. If you click View->source in your browser, you will see the frameset defenition. With frames, it is the frameset that holds the URLs to the subframes, and only the URL to the frameset will show in the browser URL window. When you hold your mouse over a linkg, you should be able to see the URL that will be fetched hen you click that link in hte lower left of your browser window (IE anyway). This link gets executed with the TARGET tag that tells the browser to shoe the results of the current request insode the specified frame of an existing frameset.
