Pidgin behaviour in linux

[Arvind Chandra]

Hi,
  I am using pidgin in RHEL 5(32 bit) and it works great. There is something which I messed up and not sure how to revert back to old settings. 
  Normally when I use to start pidgin and then close the client by clicking on close icon in it, it used to go to the task bar in my gnome desktop. And that was very useful as I am still online. I can go offline or away by right clicking on the icon. So when I get an IM it will change it's look and I can start chatting. 
  Now when I close the client it just goes away and log's me off. 
  How can I go back to old settings is there something I need to do?
Thanks
Arvind
