Hi, I'm fairly new to Twisted and trying to get a twisted reactor to work with wxPython. I'm trying the perspective broker examples, and when I try to do: def OnFileitems0Menu(self, event): self.Close(true) reactor.stop() It shuts down the program fine, but then when I try to run it again I get: twisted.internet.error.CannotListenError: Couldn't listen on any:8800: (10048, 'Address already in use'). As an error. I can manually stop the process and then it will work again, but I don't know how to release the port when I shut down the program. Am I missing something obvious? A search of the archives hasn't shown me any way out. Peter __________________________________ Do you Yahoo!? Yahoo! Finance: Get your refund fast by filing online. http://taxes.yahoo.com/filing.html
