	The setting of windowKind must be done regardless (as far
as I've been able to determine) how the window is going to be used
if you expect/want it's events to get back to the DA.  In fact, some
applications will probably puke all over you if you don't since the
will be trying to do updates on windows which they don't recognize
and/or know what to do with.  How to prevent your application from
being bombed by some DA that doesn't handle it's windows correctly
is another problem entirely.  Basically though you should ignore
any window events that don't belong to a window you know about.
