Answer 1

The suggestion to stop the thread generating the messages is not acceptable. Delegates can be multicast. Because one listener does not want to listen to the band, you don't shoot the band members. Since the framework doesn't provide any easy way I know of to clear the message pump of those event messages, and since the form does not expose its private property that lets us know the form is closing: Set a flag on the IsClosing Event of the window after you unsubscribe or stop listening to the events, and always check this flag before you do a this.Invoke().
