I suspect you are calling updateMouseTrap somewhere and the third
parameter to that is not correct. According to the docs, that parameter
can only be one of two things: An integer (a control ID) or a 4-element
sequence in which each element is an integer. This is supposed to
be a 'rect' specification in the form {left, top, right, bottom}.

That was a good clue. Actually, it was when I created the mouseTrap,
I was passing a sequence of four sequences (points)... But that's
fixed and it works.
Now, when I click on the mouseTrap area, wouldn't returnValue(-1)
prevent the click from going through to the underlying controls? It
doesn't seem to be stopping the click. I get a click response for
the mousetrap, but the underlying window also receives the click
although I've used returnValue(-1) in the mousetrap click code.

Great!

Well it has never been documented that that would be the behaviour of
a mousetrap event handler. But if that is a need you have, I can see
what I can do.

Okay, I assumed it would behave as any other control... Let me tell you
what I'm doing and maybe you can offer a better way.
I'm displaying a bitmap on a child window ('cuz I need to receive
events for that bitmap). I can then place another graphic on top of
that bitmap. I want to be able to click and move the graphic around.
I've put a mousetrap on top of that graphic and it receives the
click event and I will no doubt be able to move it around. But I
don't want the underlying controls/window to receive the click.
What do you think?
