Diagonal Movement??

Bredhouse

Hi

I have a game where you have to move a square to a door at the bottom of the screen to continue to the next level. The controls are 4 buttons at the bottom of the screen; left, right, up and down, the buttons are fine when testing on the mac but when I test the game out on the iPad and you press two buttons at the same time e.g Down and Right, the square starts to move faster in a diagonal movement and I only want it to move on the x and y axis (left, right, up and down) only, not diagonal. Can anyone please help me out?

Thanks.
