Page navigation & query_posts

Hi,

I’m using query_posts(‘cat=-7’) to exclude posts from category 7 in my index page. Then, I’m using posts_nav_link for page navigation. The problem here is that I only get the most recent posts displayed.

I have tried setting the Options > Reading > max number of posts per page to 3, to -1, to 10 and also specifying them in the query_posts(‘cat=-7&posts_per_page=3’) function but I don’t get the expected behaviour.

Any suggestions?

Thanks in advance,
Felix.
