Mac OSX issue with user input in game

Hi all,
I’ve recently switched over to a Mac; I was able to import my jme project built in Windows 7. Everything goes smoothly during clean and build. But, during run time, the user input listener seems to be ignoring keyboard entries (e.g. WASD and touch pad). Please let me know if you have encountered this before. Thanks.

These are the key mappings which work OK in Windows but not OSX. What am I missing?

inputManager.addMapping("Left", new KeyTrigger(KeyInput.KEY_A));
inputManager.addMapping("Right", new KeyTrigger(KeyInput.KEY_D));
inputManager.addMapping("Up", new KeyTrigger(KeyInput.KEY_W));
inputManager.addMapping("Down", new KeyTrigger(KeyInput.KEY_S));
inputManager.addMapping("Jump", new KeyTrigger(KeyInput.KEY_SPACE));
inputManager.addMapping("Shoot", new KeyTrigger(KeyInput.KEY_X));
inputManager.addMapping("Choose", new KeyTrigger(KeyInput.KEY_E));

My players have never had a problem with my keys on Macs. Must be something environmental I guess.
