[ubuntu] Pidgin icon in notification panel

Of course in Pidgin settings I choose "always show in the notification panel", but it changed nothing. The other problem is that I'm unable to change the size of the panels (both top and the bottom panel), which was not a problem in the older version of Ubuntu. Is there any way to deal with th (Hardware)
