alt+tab macro with saitek cyborg keyboard

[Cecoknopfler]

Hello there, I am trying to make a macro button with my saitek cyborg v7, but I can't understand why it doesn't work.... I want to make a alt+tab macro, with the win7 effect to switch windows, but it doesn't work, and neither the windows left button+tab works. Do you know why? have any ideas how to make this work? thanks
