Header menu doesn’t show on single post

Hi,

I’m having problems with a header menu. It works great on the main page, but it doesn’t show on single posts.
I’m already calling the narrowcolumn instead of widecolumn from single.php.

The header menu is a div containing some links and a search filed.
It look like it’s completely ignoring the list of images/links, but still showing the search field…

Here is the main page:

And here is the single:

Thanks in advance.

Have a great 2010!!!
