Have installed almost spring 1.3 on a site I'm doing for a charity - http://www.thuso.org
The theme is unaltered.
The site uses many pages. The issue is that if you click on a page link on the sidebar, the resulting sidebar no longer shows link categories (that is, categories of static pages).
The sidebar, I believe, should always be the same, whether viewing a blog item or a static page. But it's not. If you try it, you'll see the sidebar shortens considerably.
When switching to a standard theme, the issue disappears, i.e. the menus stay constant.
Have tried to contact Becci, but no joy.
