pidgin does not open window dialog with yahoo's link for user authentications in it

[Vu The Cuong]

Hi all
I just install pidgin 2.3.1 in centos 5.1 ok.
I logged on to my yahoo account. But it's is strange that when I connect to
chat room,
pidgin does not open window dialog with yahoo's link for user
authentications in it so that I can click on this link
to authenticate me.
Anyone could help me?
Thanks
Btw in freebsd 7.0 with Gnome 2.20 installed from ports, pidgin does open
that dialog for me.
What I'm still missing in pidgin of centos 5.1?
