@!$~ help please!!!!

Hope you can help... Whenever I try to add a discussion topic to a group, under the access list at the bottom of the add topic page, Private, Public etc on the drop down list, I only see the groups I have created, none of the groups that I also belong to but didn't create don't show up, I tested this on Admin and non admin accounts and its the same. I've also tested uploading files and the access list is the same, any ideas as to how this can be fixed... My thanks in advance. Best Regards,Chalkiex. www.gimmethedirt.com
