3D card problem
Choregraphe does not work with all the 3D card. If it crashes at start up, it probably means that there is a conflict with your 3D card. Please update your graphics card driver and try again. If it does not work, you will see a pop up with an internet link to the supported graphics card. You should check it out (http://www.ogre3d.org/wiki/index.php/Hardware).
