Show wp-dTree on Posts sidebar

WP newbie, be warned.

WP 3.03, using Unnamed Light 1.0 theme, using wp-dtree 4.2 plugin.

This plugin is exactly what I need. I add its widget to Sidebar 1 in my “Appearance/Widgets” admin page.

It shows up perfect when I am on first page of my WP site. I see my categories and associated posts in the right sidebar.

When I click a post though, the sidebar changes and the navigation is lost.

Is this normal WP behavior or a function of my template?

I’d love to have my wp-dtree navigation tree appear on every Page or Post.

How to?

Thanks,
Steve
