You have odd users (..but I bet they will still surprise you!).

...if you do not wish to act on those events inside
the frame - don't.  "ignore them and they'll go away"..
E.G. You might check the bounds of the frame and
ascertain if the point at which the mouse event
occured was *inside* it (before acting on it).
