Indeed it does - cos OS X is actually my main development platform! :)

It isn't Blitz per se that's a problem - not the bottom of the
stacktrace mentions GenericWorker which is nothing to do with the Blitz
codebase.

Gregg is heading in the right direction - I'd recommend using "lsof" to
figure out who's got hold of the port in question.

Cheers,

Dan.

P.S.  Note also that for Blitz specific questions (which this actually
isn't, yet) you should post to the blitzjavaspaces-users list over at
sourceforge:
