[CentOS] Evolution Question?

[Jeff]

I have a CentOS 5.3 Desktop and use Evolution to read mailing lists . 
When i move from one read letter to another(either deleting or clicking 
next  the Message pane flickers. How can i stop this because it is hard 
on my eyes when i have a few emails to read?
