MAJOR (Q&A)! member sees all questions from back end - how to hide it?

Hi!

The plugin works fine but the problem is that when I login as a regular member I can see ALL the questions/answers from the back end (dashboard) not just this one member's questions/answers. I can even edit pending questions even though that role isn't activated.

Simply - How can I hide /wp-admin/edit.php?post_type=question ? from the dashboards (except for the admin of course)?

Thanks!
