Thanks for your reply Claus. Here is the code I use (well,
a part of it, 'cause it's too long to by send to the net).
The weird thing is that it works with button 1 (the left
one) but not for button 2 (the right one).
In fact, the right one seems to be the same as the joystick
'fire' button.(am I right?)
I wanna put a other switch at the joystick's place to start
a chronometer with the foot ('cause hands are occupied by
a blood analysis, but that's an other story).

Thanks in advance for your help.
