Wiimote IR unuseable with Hybrid Wiimote mode

[Ganz]

Hello there!
I'm not able to use the Wiimote (RVL-003) with emulated Nunchucks. Only the IR refuses to work, buttons and rumble are OK! The pointer (hand with number 1) always appears, even if the remote isn't pointed to the IR source. If I select real wiimote, IR also Works, and I can navigate in the game menu. I don't have a real nunchuck, so I must use my Dualshock 3.

Thanks for you're help!
