Current page highlight on TwentyTen theme menu

Started with WordPress 3.01 and the “TwentyTen” theme.
I modified the menu (on header) colors to fit my website theme better.
At that time, the current page, IE. “Home” was highlighted in BOLD.
Don’t see that now, The CSS classes for that are not called.
Looking at the page in source view, the “current” classes are never called in the page source. My CSS for that is listed below:
#access ul li.current_page_item > a,
#access ul li.current-menu-ancestor > a,
#access ul li.current-menu-item > a,
#access ul li.current-menu-parent > a {
color: #8b4513;
font-weight: bold;
}

If I return to the original un-modified style.css I get similar results with the original colors.
