I think I've nailed down the issue with logins being expired too quickly.
I've made sure the cookies are stored with a 30 day expiration after last visit.  I've also stored security keys in a secure folder on the server so hopefully logins should persist even when I restart the server software.

I don't know how many people found it annoying, but I am hoping that should now be done. please let me know if you have issues with it.
