Windows Live Mail Animation Speed

I have Windows Live Mail installed on a new Win7 system.  I use WLM to access several different email accounts.  When I switch from one inbox to another the email titles in the Message List do a fade/slide-in visual effect.  How do I speed up (or eliminate) that visual effect?  It is quite annoying, especially since I just did a major hardware upgrade and the animation negates any improvement in speed.
