I've updated the role of the contributors to include the ability to upload media, however now they are unable to see all posts in the post list. Before Role Scoper, Contributers can see all posts but only edit their own. But when I updated they now can only see their own.  Suggestions on how to change this?  I don't see an option in the role selection check boxes for view all posts or something like that. I believe it's a default permission for Contributors in WP.
