On my mac, the window summoned by a double-click after running Performance Report has no close box, and no close buttons, and no obvious way to dismiss it. It turns out that choosing "Racket > Quit" from the menu gets rid of it, but on a Mac, this is *severely* unintuitive, as it appears that you're closing the whole application. Am I doing something silly?
