Storing cookies on a PC from my web site? RESOLVED

[Wokawidget]

When I store cookies using:

If ValidateLogin(txtUsername.Text, txtPassword.Text) Then
                objTicket = New FormsAuthenticationTicket(txtUsername.Text, False, 5)
                objCookie = New HttpCookie(".ASPXAUTH")
                objCookie.Value = FormsAuthentication.Encrypt(objTicket)
                Response.Cookies.Add(objCookie)
                strReturnURL = Request.Params("ReturnURL")
                If strReturnURL Is Nothing Then
                    Response.Redirect("Main.aspx")
                Else
                    Response.Redirect(strReturnURL)
                End If
            Else
                lblMessage.Text = "Incorect username/password"
            End If

Then IE MUST have it's privacy settings to LOW (medium is default) otherwsie the cookies don't work, and I get redirected back to my login screen....???!

What am I doing wrong?
