Original Title: Internet Explorer and Windows Live Mail

Since downloading Internet Explorer 8 my Windows Live Mail no longer retains addresses in groups. When I click on Contacts, all my groups are displayed including all the names asigned to the group. However, when sending an email, the group name appears in the To box, but none of the names are included. I've tried to redo the groups with a different group name, but when I try to send an email to the new group, the names and addresses don't carry over. How can I correct this problem?
