[Mark Smith]

Hi Bob,

If you have a bit of time, could you tell us a bit more about how?

Thanks,
Mark

Even multiple behaviors in the same script perhaps each with their own 'mouseUp' handlers and then you can set the behavior of an object to a behavior name and done. Obviously, any messages (i.e mouseDown, mouseUp, etc. etc.) in the behavior block should never received a mouseDown, mouseUp, etc. message unless sent to the object tat have the behavior assigned to it.
