I just committed an update that should resolve the layout issue you are seeing. I posted some pre-release 2.0 binaries here that you can use to verify the fix:
http://ixnay.biz/pivot-2.0/ You should be able to use the BoxPane approach, but TablePane should be OK too, if you prefer that. Let me know if this does not fix the problem. Also, with respect to: > Meanwhile, do you have a suggestion for how one lays out two buttons in a > horizontal row and achieve a pleasant amount of space between them, perhaps > even nicely balanced independent of window width (e.g., equal amounts of > whitespace to the left, to the right, and in between)?

I had suggested that you use the "spacing" style of BoxPane to define an appropriate distance between the buttons. You can also use the "padding" style of BoxPane to apply spacing around the buttons. In most cases, I'd expect this to be sufficient - as the user resizes the window, you generally don't want to increase the distance between the buttons and the edge of the window (assuming that they are right or left aligned - if centered, the left/right padding is dictated by the size of the window anyways). If you do want the padding to scale with the size of the window, you could use a table pane with relative-sized columns, though I think that might create a visually confusing user experience. G
