Incorrect User Timeout (expired token) Redirect?

I have disabled the stock mod_login and enabled mod_cblogin. The redirects for mod_cblogin work fine when a user logs in, or manually logs out. However, if a user doesn't manually log out, doesn't leave the site, powers down, and then powers back up again after the token has expired, then the component com_login dialog appears as content. Shouldn't CB have control at that point?
