Amigavision (Windows) two buttons joypad

I always emulated Amiga with Winuae on Windows and never had a problem with my USB XBOX(ish) joypad working with the two buttons expected by games that support a secon button (e.g. Lionheart).

Recently I've tried Amigavision and it never seems to recognize the second button even in games that natively support it.

Have you ever faced this problem?
