Disable selection of a visual

Ok I figured out the workaround.  Since it is disabling selection of visual is not possible, use the shape widget to build the background of a filter pop up but add a bookmark action to the background shape widget where it will show the book mark page you want to show.  So even when the background is clicked the action will take you right back to the screen with all widget showing the correct Z axis and the background shape will never be able to come forward. I will post up a sample pbix file if my description is not clear here. Let me know, and hope this helps.
