Scheduled Post Problem

A scheduled post appears on the home page–as it should.

The problem is that it does not appear in the sidebar unless the article is re-saved. Re-saving the article before it is scheduled has no effect.

This is the code that is suppose to make the post appear–but does not.

wp_list_categories (‘sort_column=id&child_of=8&title_li=’);

Is there any reason that this code would cause the strange behavior? Is there anything else that could be causing the problem?
