[Bug] Cookies

Hello,
I’m using WP 1.3 A4 and found a bug. In the meta, when you re-visit your site, it will say:
Register
Login
etc..
then, when you hit login, you are logged in and takes u to the admin CP.
Now, If you refresh your site pages, it will say:
Site Admin
Log Out
etc…
How do i fix this? I’m using FX 1.0 Final and added my site so it accepts cookies but it still isn’t working…If you want the link to my site, let me know.
