The XML sitemap worls well, but the html sitemap has a mind of it's own.
Currently my html sitemap is correct excep for one menu item, for which it obstinately refuses to expand and show the article links. This category/menu has exactluy the same setting as the other ones, but it won't expand.
Sadly I'll have to go look for another extension. One that expands ALL categories.
Pity about the bad transition to 2.5, xmap for 1.5 was much more solid.
