[Plugin: scbFramework] Query Manipulation doesn't work within widget?

I just made a plugin with the scbFramework so that I could see the $wp_query within a posts_where filter and it works perfectly so far using WP_Query and query_posts but it doesn’t seem to work when I call it within a widget. Does this have anything to do with the scbFramework and is there anything I can do to filter queries within a widget?
