Does anybody know if (H)OpenGL can recognize a mouse movement even if the mouse cursor doesn't move? For example, suppose the mouse cursor is placed at the top left corner of the screen, and I move my mouse to the top left corner direction. The mouse cursor won't move, although the mouse WAS moved. Unfortunately, the "motionFunc" and "passiveMotionFunc" are related to the new position of the mouse cursor, rather than the mouse movement... (in the Allegro library, this is solved by a thing called "mouse mickeys").
 
Thanks a lot,
Andre W B Furtado
