FWIW, IIRC this inconsistency was intentional an I believe for a very good reason. I thought we had documented it at the time but I can't dig it up easily right now. An uncaught exception indicates that the application is in an undefined state. For certain type of applications (like viewers) this can be ignored. For editor application this could mean that the document being edited could be corrupted and saving it cause data corruption. This thread is the only reference I found in which we suggested some type of "Developer-Mode" which indicates that "I know what I'm doing, let me debug, will you?!". http://lists.gnu.org/archive/html/discuss-gnustep/2004-10/msg00092.html I still believe that handling generic handling of exceptions in the runloop is a dangerously wrong and an implementation detail that we shouldn't try to be compatible with. But others may disagree. Cheers, David _______________________________________________ Gnustep-dev mailing list Gnustep-dev@gnu.org http://lists.gnu.org/mailman/listinfo/gnustep-dev
