In many dropdown lists, you select it and press the DELETE key to remove it from the list. I can't test this in that program since I use GAIM where required for IM stuff.

Is there any way to remove the EMAIL ADDRESSES stored in MSN Messenger [version 6.2.01333], shown when you see the SIGNIN window and you can scroll down through a list of Email addresses. I want to delete the scroll-down list.
