[Evolution] How to set preferences for an account on gnome 3(and save it)

[Monnand <monnand gmail com>]

Hi all,

I am using gnome 3 with evolution 3.4.3. I want to set the preference
of my account and save it. However, after all setting works done, I
cannot find any "save" button on the preferences setting window. I
pressed ESC and every change was gone.

I just want to know, how can I change an account's preferences and
save it? Anyone can help?

Regards,
