Is there a simple way to do this?

Bah! =(

It can make things extremely complicated and cumbersome, especially when
your code is basically straightline video mode setting and window
creation.
Anyone have ideas for a simple solution? Right now I've hacked SDL so
that it always starts in windowed mode before going into fullscreen.
For some reason this problem only manifests itself if I start in
fullscreen then go into windowed, as if the act of window creation sets
up some basic state that the AppKit needs later.
