If I declare an event using a delegate and I add event listeners to the event, what happens if one or more of the event listeners are distroyed?  Do I have to always remove the event listener from the event object, or is this done for me if an event listener is destroyed?

If this is using remoting then you definetely have to unsubscribe the event.. otherwise it attempts to send an event to a process which is no longer listening and bombs out. This then prevents all other subscribers from receiving your event. You can trap the error and itterate the 'InvocationList' to determine which subscriber is causing you the problem.

If it's not using remoting then I'd imagine that you might be lucky.. best thing to do is try it.

I am not using remoting right now, but things worked much better when I was careful to remove all delegate event listeners when they were destroyed.  I thought that garbage collection might take care of this.
