The problem is one of timing. MainMenu.nib is loaded when your application
starts up, so your defaults are being initialized too late. There are two
easy solutions:

(1) Put the preferences panel in a separate nib, which won't be loaded until
after your application has finished launching. Or,

(2) Perform your defaults initialization earlier. For example, you can do it
in main, like this:

int main(int argc, char *argv[])
{
    // initialize defaults before loading a nib that uses them
    NSAutoreleasePool* pool = [[NSAutoreleasePool alloc] init];
    [[NSUserDefaults standardUserDefaults] registerDefaults:
        [NSDictionary dictionaryWithObjectsAndKeys:
            ...., // real values go here
            nil]];
    [pool release];
    // and away we go
    return NSApplicationMain(argc,  (const char **) argv);
}
