Re: Problem with modal dialogs

[Pascal Bourguignon]

Note that there is no API  to know when a NSApplication instance is in
a  modal  loop  (or to  retrieve  the  current  modal session  from  a
NSApplication instance).  That's the reason why IMHO,  there should be
no exception if an abortModal, stopModal or stopModalWithCode: is sent
to an application!
