Duration of online members

Hi,

I have 7.0.4 and It find that the online status of a member don't last very long even if they are still logged in.

I did this :

1- I logged in as a user,

2- go to section online members 

3- see my user

4- wait a few minutes

5- still logged in

6- go back to online members

7- I don't see my profile

Is it normal ?

Where can I fix this ?

I also went to see in the database and I see 29 profiles that have the field "UserStatus" as online. and on online section I don't see any profiles

you tried to change in the administration

Settings/Advanced Settings/Other

Time period in minutes within which a member is considered to be online:1

Ok Thanks it works nicely ! ;)

Is there a way that members are online until thay log off or something like that...?
