Everytime i come to the IPS forums, im logged out even tho i said remember me in the login page. You may wanna have a look at that......

Hmm... works for me.

Could be the stronghold cookie.

Do the first 2 octets of your IP change frequently? (believe it's only the first 2 that are part of the key)

This has started happening to me since 2.2 also, I 've been logged in since about 2.03, since Tuesday, I need to log in ever time.

Have deleted the cookie, will see if that helps.

Wipe out your cookies, try fresh. :)

Indeed, just deleting the cookie for forums.invisionpower.com and restarting Firefox did the trick.
