posts_nav_link creating Moebius strip

Hi there,

I’ve posted about this before, but nothing came of it. Toward having a front page with an arbitrary number of recent posts on it, I made a home.php file and added a call such as

query_posts('posts_per_page=5');

This works as expected. However, the posts_nav_links call doesn’t work correctly. The URL returned is something like

https://www.erectlocution.com/boxing/page/2/

which only displays the same five most recent posts. Each successive clicking of “next page” results in iterative repetitions

https://www.erectlocution.com/boxing/page/3/
https://www.erectlocution.com/boxing/page/4/
https://www.erectlocution.com/boxing/page/5/

I dug into templates-functions-links.php to try and find a way to make the output work correctly, but I couldn’t figure it out. It seems as if there is a disconnect between the output of home.php and the remainder of the blog via these “next page” links as generated by posts_nav_links().

Any thoughts?
