How to use SDL with OGRE?

Question

When I go to use OGRE with SDL (as described in this article), I seem to be having trouble with a second window that appears behind my main render window. Basically, the code I'm using is this:

SDL_init(SDL_INIT_VIDEO);
SDL_Surface *screen = SDL_SetVideoMode(640, 480, 0, SDL_OPENGL);

Ogre::Root *root = new Ogre::Root();
root->restoreConfig();
root->initialise(false);

Ogre::NameValuePairList windowSettings;
windowSettings["currentGLContext"] = Ogre::String("True");
Ogre::RenderWindow *window = root->createRenderWindow("MainRenderWindow", 640, 480, false, &windowSettings);
window->setVisible(true);

The question is, how do I get rid of the extra window?

Just for posterity, I'm using OGRE 1.6.4, Mac OS X 10.6.2, and SDL 1.2.14.

I ended up figuring this out on my own. The problem ends up being that OGRE's Mac GL backend does not honor the currentGLContext option, so the best solution is to change to SDL 1.3 (directly from Subversion, as of time of writing) and use the SDL_CreateWindowFrom call to start getting events from a window created by OGRE. It should also be noted that the OGRE window needs to have the macAPI set to cocoa, or else SDL won't recognize the window handle.
