I will use one of my projects to test your theory and see if I can give you and answer. I would like to know what code you are putting in the nested master page load event. That way I can test something similar to what you are trying to do.

This is the code I tried in my IASLeftNav.Master Page_Load that didn't run:

            if (Session["mmUserSecurity_UserPk"] != null)
            {

                object UserPk = Session["mmUserSecurity_UserPk"];

                DataSet dsUser = mmAppBase.SecurityMgr.oUser.GetUserByPK(UserPk);
                string userFirstName = "Not";
                string userLastName = "Logged In";

                if (dsUser.Tables[0].Rows.Count > 0)
                {
                    userFirstName = dsUser.Tables[0].Rows[0]["FirstName"].ToString();
                    userLastName = dsUser.Tables[0].Rows[0]["LastName"].ToString();
                }
                this.lblCurrentUser.Text = userFirstName + " " + userLastName;
            }

But it didn't matter what code was there, when stepping through the code the debugger never even went to the Page_Load for this master page.
