Joystick bug with the digital pad

[Drake]

Hey!

I would like to report a little problem with the xbox 360 conitroller, especially with the D-pad. The game doesn't seem to recognize when I select 2 directions with it (for instance, up and right), and only does one of them. (In this example, when I try to do up and right, the game will only think I press "up".)
It seems to take the button in the counter-clock direction. When I try to crouch while moving to the right, Mario doesn't crouch. However, when I try to go to the left, he does crouch (and also doesn't move at all if I try to jump at the same time)

Thank you!
