One more thought: If an application throws an exception without catching and handling it, like is the case above, then this means that the application is badly programmed. A good application would catch the exception and do what is necessary in that state of of the program. In this case one can simply say the app or part of it just badly crashed; no app should behave so. Exceptions can and must be handled by the app. cu Uenal ___ xmail mailing list xmail@xmailserver.org http://xmailserver.org/mailman/listinfo/xmail
