// conversation events within the ConversationAdded event handler.
//
// This is required to avoid timing issues which would cause the application to miss events.
// While this handler method is executing, the Lync client is unable to process events for
// this application (synce its thread is running this method), so no events will be lost.

// caught the first time they occur.
//
// We want to show the availability of the buttons in the conversation window based
// on the ActionAvailability events. The solution below uses a lock to allow the window
// to load while holding the event queue. This prevents events from being raised even
// before the user interface controls get a change to load.
