Hi,

 

 

The messenger do not allow multi-instance of same PC .

 

So please use FireFox to test another messenger . or use another PC.

by the way , the

        public override bool IsAdministrator(string id)
        {
            MembershipUser User = Membership.GetUser();
            return (User.UserName == "Admin");
        }

is wrong.

 

the id shoud be "User:loginname" , so please do not use Membership.GetUser() to get the current user.

use the argument id to find the user , and then return true if the id is admin.

 

Regards , Terry .
