Contacts- Can't add a contact to a group
I've created the group (File-->New Group). Tried creating it in the iCloud section of the sidebar and "On my Mac". Same behaviour.
I select a contact in my "all contacts" highlight and drag over to the group in sidebar that I want to add it to, BUT it bounces right back and will not add to the group!!!
