Relax.
I'm sorry but this is simply not where I want to go. I'm not interested in writing code that does something that the system already does. At the same time, I want to provide that missing functionality on older versions of Mac OS X without having two versions of source code, if at all possible. Consider it an academic exercise. It is not the end of the world and I am not the devil.
I do appreciate everyones responses, though. This is a nice place to learn new things. I reserve the right, however, to set my own policy with regard to what I will create and how I make use of our combined expertise in doing so.
Have a great day, fellas.
-Michael

If anyone's interested in the topic they can search for the many, many previous messages on this topic here and in xcode-users and objc-language. And if anyone really needs to post new stuff about it, please use objc-language as the forum.
