If you feel strongly about this NULL, go ahead and leave it, but given that it's
in the destructor and no dependent code could run after it, it is probably just
a wasted couple of bytes.

Done.

Did you want to call Close() after this?

I was under the impression that the widget is already in the process of being
closed.  I'll take another look.
