// The hotkeyhandler is a small, invisible window which handles the following things:
//
//    a) event notify stuff, messages posted from the popups to avoid threading
//       issues.
//
//    b) tray icon handling
//
//    c) send later job management. Periodically process the queue of open
//	   deferred send jobs.
