Is there a way of signing in to MSN Messenger using the MSN Icon/taskbar
without it leaving it's evidence in the sign-in window (drop down menu when
more than one account) I know how to delete the sign-in name after signing
out of the account but wondered if there is a way to permanently omit an
account from this drop down list)

(I know about using the browser and www.hotmail.com/uk but this still leaves
evidence of an account being used when using a webcam)

Thanks.
