breadcrumbs feature

It seems your content is not hierarchical in more than one level. The breadcrumb only links back to home because all your primary sections have no parent page in themselves, thus only display a link to the global parent (home).

If you wish to display the current page in the breadcrumb trail, you need to replace the breadcrumb function in template.php in the Framework theme directory.
Find the function that looks like the following, and replace it with this: (note there is only two lines difference, the php function, and the comment explaining it)

/**
 * Return a themed breadcrumb trail.
 *
 * @param $breadcrumb
 *   An array containing the breadcrumb links.
 * @return a string containing the breadcrumb output.
 */
function phptemplate_breadcrumb($breadcrumb) {
  if (!empty($breadcrumb)) {
// uncomment the next line to enable current page in the breadcrumb trail
//  $breadcrumb[] = drupal_get_title();
    return '<div class="breadcrumb">'. implode(' » ', $breadcrumb) .'</div>';
  }
}

Uncomment (remove the "//") from the $breadcrumb[] = drupal_get_title(); line as it says, and that should fix your breadcrumb issue.

---Also---

I just remembered that this function was only really needed for Drupal 5.

The following module for Drupal 6 should do the same thing, and give you a few more options.
http://drupal.org/project/menu_breadcrumb

I'm not sure why this would be. Did you try either of the methods I explained?

Try installing this module.

If your sections are based on categories/taxonomy, try installing a module called Taxonomy Breadcrumb
