Contex.User.Identity.Name Changes When New User Created

 I use a Login Control for the user to login to the web application and I have a create user wizard for an admin to create new users as needed, once logged in.  Prior to creating any new users, Context.User.Identity.Name holds the username of who is currently logged in.  However, after the user is created, Context.User.Identity.Name contains the username of the newly created user.  I have searched and searched throughout my code with nothing alterting the value.
 
Any ideas why is this changing and how to correct this problem?
 
Thanks!
