[Goad]

I use the SDL framework that comes with the demo, and can run in full-screen mode.

I also experience incorrect mouse position in windowed mode. It is not random, it is inverted (move the mouse up, and where the app thinks the pointer is moves down). But left-right is not inverted. An underlying byte-order issue? Perhaps.

I apparently have some Version of sdl on my machine somewhere as the app will start up without the SDL framework, and has correct mousing in windowed mode. But, it crashes when you get to "start game."
