If you move your bookmarks toolbar to the menubar and have the menubar hidden, pressing alt to show the menubar and clicking a bookmark doesn't load that bookmark. Instead, the menubar/bookmark bar simply hides. The work-around is to not hide the menu-bar but as that's the new default for windows 7, this seems less than ideal Tested on today's trunk build with windows7. This is customized, for sure, but still a basic behavior that's broken.
