[Evolution] is there a setting that controls this....?

[Reid Thompson <Reid Thompson ateb com>]

I'm wondering if I accidentally activated a setting.
Evo 3.2.4 built from gnome-3-2.
Starting last week, when a new email arrives, evolution automatically
scrolls the message list view to the latest arrivals -- Can I turn this
off?
It's a pain when email arrives while i'm in the process of looking at
older email and the window scrolls down.

thanks,
reid
