I'm not really sure whether this is a bug or not, but here it goes.
When using custom names under msn messenger, in the screen "send an instant message" still appears the email address of the people that I have in my contact list, instead of appering the the custom name I use for them.
If this is a bug, try to fix (although it seemed to obvious to me), if not and there's no nothing to do, delete this thread!
Tnhks in advance.
