What method should be called to deactivate an app right after it's launch in applicationDidFinishLaunching: delegate method has been called? Or maybe there is a better place to do that? The documentation for deactivate method for NSApplication says that I shouldn't call this method directly since AppKit knows better how to deactivate stuff.
Maybe using -[NSApplication hide:] would work, or perhaps activate another app using -[NSRunningApplication activateWithOptions:] (10.6 only, tho). However, I don't foresee many problems with using deactivate:.
