Re: Problems with Launchd Daemon

Unfortunately launch daemons can't be Cocoa applications or 
applications that rely on the window server in general (and other 
higher APIs).  You'll be better off launching it as a user login item 
(accounts prefs).  These are launched in the user's context and after 
the window server is loaded.
