This may not actually be an API question - my apologees if this is the wrong place for this question.

I'm trying to simply approve users as they are created. For some reason, IsApproved just refuses to be set to true. Before you say, "You have to call Membership.UpdateUser()" . . . I have already tried that. When I step through the code, IsApproved gets changed to true on the member object when I use mem.IsApproved = true, but then when I call Membership.UpdateUser(mem), it reverts to false. From everything I've read, this SHOULD work, so if you have any idea why it's NOT, I'd appreciate the insight.

Here's my code:

protected void btnSubmit_Click(object sender, EventArgs e)
        {
            if (Membership.GetUserNameByEmail(txtEmail.Text) == null)
            {
                MembershipUser mem = Membership.CreateUser(txtUserName.Text, txtPassword.Text, txtEmail.Text);
                mem.IsApproved = true;
                Membership.UpdateUser(mem);
                CreateNewProfile();
                Roles.AddUserToRole(txtUserName.Text, "Customers");
                if (cbxCorporate.Checked)
                {
                    Roles.AddUserToRole(txtUserName.Text, "Company");
                }               
            }
            Response.Redirect(umbraco.library.NiceUrl(1063));
        }

And the membership section of my web.config.

<membership defaultProvider="UmbracoMembershipProvider" userIsOnlineTimeWindow="15">
      <providers>
        <clear />
     <add name="UsersMembershipProvider" 
           type="umbraco.providers.UsersMembershipProvider" 
         enablePasswordRetrieval="false" 
          enablePasswordReset="false" 
          requiresQuestionAndAnswer="false" 
            passwordFormat="Hashed"
           minRequiredPasswordLength="8"
         minRequiredNonalphanumericCharacters="0" 
         umbracoApprovePropertyTypeAlias="approved" />
      <add name="UmbracoMembershipProvider" 
         type="umbraco.providers.members.UmbracoMembershipProvider" 
           enablePasswordRetrieval="false" 
          enablePasswordReset="false" 
          requiresQuestionAndAnswer="false" 
            passwordFormat="Hashed"  
         umbracoApprovePropertyTypeAlias="approved"
            minRequiredPasswordLength="8"
         minRequiredNonalphanumericCharacters="0" />
        
      </providers>
    </membership>

Incidentally, I am not sure whether I need both of those providers. They have both always been there, so I didn't mess with it.
