Forum Who is Online - User Doesn't Disappear When Browser Closed But Still Logged In
 

How can I have it that when a user leaves the site but is still logged in (didn't log out before leaving) disappears from the "Who Is Online" list?

I logged in on my site with a test account (other browser than my original account) for testing things. Then I closed the browser (didn't log out). As I woke up like 10 hours later the test account still appeared in the "Who Is Online" list.
