No IP checking but cookie (Help!)

Sorry my english...

I got all working fine, but:

I DON¨T want IP checking, only cookie. There are many people at office with lan (same IP for all) that can´t vote.

I've tried these settings:

Logging ON
Check: IP Table

People can vote only once, but if you have many PC in lan and someone has voted.. you can´t

Logging On
Check: no check

Everybody can vote several times, no matter IP, pc, etc...

I've tried "require" and "include_once" for poll_cookie.php and see no difference.

So, what I really need is:

People can vote only once per PC, no matter IP
A cookie restriction only.

Thanks!!!!

please...

Logging can be left on.
Turn IP Table off.

Include poll_cookie.php in your pages as well as booth.php.

Thus, voting is controlled PC wise rather than IP wise which can multiple PC's.
Only problem is is that people can clear their cookies and vote again.
