Ok, so I'm using the new TwentyTen theme and getting familiar with it. From what I understand you create a custom menu and picks it's spot, which was done with no problem. The menu consists of all of my top level pages, but only one page gets the current-menu-item class added to it's list item when you're on that one page. The rest of the pages do not get assigned this class.
Strange isn't it? All of the pages are top level, no children, and I've viewed the source code rendered on all of them and no current-menu-item.
Is any one else having this problem? Just an FYI, this is a local install on MAMP.
