ChaseCam strange behavior when recreating

Hi all,
I got a problem with the ChaseCam when recreating it. I already implemented saving and loading in my little RPG, but when I load a game and then load another one, the ChaseCam behaves strange. It somehow rotates around the z-axis. I create it with input, but also unregister all triggers and remove it as listener:

[java]
inputManager.deleteMapping(ChaseCamUp);
inputManager.deleteMapping(ChaseCamDown);
inputManager.deleteMapping(ChaseCamMoveLeft);
inputManager.deleteMapping(ChaseCamMoveRight);
inputManager.deleteMapping(ChaseCamZoomIn);
inputManager.deleteMapping(ChaseCamZoomOut);
inputManager.deleteMapping(ChaseCamToggleRotate);

    inputManager.removeListener(this);[/java] 

Does anybody know a solution for this problem? Or do i have to create an own ChaseCam or make the one i use static and reuse it again and again?
