Added note: they should also rewrap/scroll usefully. While testing this to see what you experience, I scrunched my window narrow enough that on the top navbar, the post/reading page/invite someone links were over the Dreamwidth logo at the left...which links to the Dreamwdith main page...which took precedence over their links as far as I could tell (or just made them really hard to target, as well as really hard to read). (I'm in tropo purple.)
