users complain, "Already logged in"

Hi,

Migrating from dd-wrt to coovaAP.
Everything fine, except some users complain they get the message "You are already logged in" while surfing the net. (For example, when opening a new browser window)
I'm using the hotspotlogin.php script originally written by Sean Bracken.
Simultaneous-use is not set so this can't be the problem.
I never experienced this problem with dd-wrt and the login script hasn't changed.
Anyone who has a clue what's going on?
I need to solve this quickly, so please help ;-)

Many tnx
Kind regards,
B.

PS Users started complaining after I installed the latest svn.
This can be coincidence though, but maybe its worth to mention.

Re: users complain, "Already logged in"

I changed my login script a bit.
Lets see what it brings us now...
All suggestions are welcome of course ;-)

EDIT: So far so good :-) I just disabled the 'Already' stuff in the script and everything seems fine now. Simultaneous-use is set on the radius now which is prefered anyway.
