I posted this here, and I've posted it to comp.windows.open-look.
Let me try again.

I believe that this problem is directly responsible for the misbehavior
of my application under OW2.0.  In particular I am getting *lots* of
situations where button clicks are being delivered to the last item I
clicked on rather than the item I just clicked on.  This situation can
be fatal to the user (click on a delete button, go somewhere else, click,
and it deletes again).

Is there anyway my application can work around this problem?  Maybe
by intercepting events and inserting some synthetic ones?  Barring
that.  When will OW2.0 be fixed?

I'm not sure which upsets me more: that people are so unwilling to accept
responsibility for their own actions, or that they are so eager to regulate
everyone else's.
