In an idle moment (Opps!), i added my own details as a trial contact into
windows messenger V 4.7. After trying something out, I tried to delete the
contact but I can't. If I selec the required (own details) contact and
right-click and pick delete, as expected I'm prompted to delete it YES or NO.
However, If I click YES, I get another message that says '(name) contact
could not be deleted. Please try later. If I press OK then messenger is taken
off line. When I log back on the details are still in the contact list.

How do I correctly delete contacts? Is this is known issue?
