There is so much goin on on this thread I figure I ask if it has already been discussed.
The checkboxes do not seem to work at all. I have a custom post type, and when adding the widget, I am trying to search three different taxonomy categories I have created, but when I try to select 1 from each it just shows all the posts. If I try to select one, it shows posts that was not related to that category. Is this a issue that has not been fixed.
