Does it only mean that the file was originally written by the Open Source Foundation, or does it also automatically mean that it is licensed under the license that you can see e.g. here: http://kernelsource.svn.sourceforge.net/viewvc/kernelsource/OSF-Mach/6.1/os…) The reason that I'm asking, is that for our compiler port for targeting the darwin/arm platform, I have to distribute a translation of Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.1.sdk/usr/ include/mach/arm/_structs.h (in order to be able to properly deal with signals) I cannot find any document anywhere explaining what this marker means. If it does mean that it is licensed like the Mach kernel sources on Sourceforge, then there is no problem for me to distribute the file (the license forbids taking away that permission, and the iPhone SDK license agreement also explicitly mentions that in those cases the NDA/ no distribution/no derivative works/... requirements do not apply).

Maybe it's better than when I last tried it (a year or so ago).

The crash log appears to live under /Library so this application isn't being truly run as a particular user, at least not in the way it normally would. As a result I think all bets are off having it work consistently ... depending on how it was coded / what frameworks it depends on. You really should use a launch agent to launch this type of thing in a users aqua session and not a daemon. Daemons live in the root session and don't have reliable access to the window server and this software appears to require such a connection, it is using AppKit for example. -Shawn _______________________________________________ Do not post admin requests to the list.
