Hi Randy, Could you maybe send me your MailDemo project as it is now? I think we'll be able to resolve it faster that way :) About the debugging, this isn't possible with xcode. I would advice using ruby-debug, http://www.datanoise.com/ruby-debug/, which means that you'll have to start your app from the terminal and not from xcode. Also I now see that this mail is going to the devel list, which is not the place to discuss this. So shall we send any new emails about this to the rubycocoa-talk list?
