I wouldn't rule out that there are still bugs related to BScrollView, but from your description I'd say that the grid view has a maximum size limit that forces a maximum size limit on the scroll view. So what you're seeing is the scroll view having hit is maximum size and its parent view having no other choice than to center it in the available space. You should check what is causing the grid view's maximum size limit and try to remedy that, e.g. by adding glue. If that's not desirable for some reason you could override the maximum size limit on the grid view or on the scroll view (with different results). Setting an explicit alignment of B_ALIGN_USE_FULL_{WIDTH,HEIGHT} on the scroll view is yet another option. The size limit will still be propagated to the parent view, but the scroll view will use all space that is available (instead of being centered in it). CU, Ingo
