Has anyone got this before? I get it from running the iPhone Simulator from within Xcode over and over again. Sooner or later I get an error message from Xcode saying it can't launch the simulator and when I get the error message, I am unable to launch ANY application at all that isn't already open. For example, if I have Firefox open, I can still use Firefox but any app that isn't open already, if I try to open it I get an error message stating that the application cannot open and I get the error -10810 message. Only way I can fix it is to logout and log back in but even then it's flaky. I have to reboot my entire machine.
