[Plugin: WordPress Loop] How to I set a permanent posts list

Hey.

I’m trying to use WP Loop, as a widget on my sidebar, in order to populate an automatic menu, for quick access to posts, within a certain portfolio category.

I managed to get the WP Loop to show the posts in the selected category.
But, when I select a certain post, and “enters” in, the sidebar (WP Loop) changes. it shows the post that I am in.

How can I set a permanent list of the posts, so, no matter when i’m in, or in which post, the sidebar (WP Loop) will always shows the list of posts that are in the selected category?

Thanks.
