[maxmsp] "nopointer" problem with wacom on intel

Hi everybody,

I recently opened an old 'wacom' patch in Max 4.6.3 on my brand new MacPro and I'm having some problem with the mouse pointer.
On my G4, I had no problem; sending the message "nopointer 1" disconnected the wacom from the pointer. But since I've tried it on  intel, the message doesn't work with the latest Wacom driver; I have to install an older driver and it works. But when I restart the computer, the pointer is again connected to the wacom.
I have to install again the older driver to make it work again... Pretty frustrating, isn't it ?
Did someone experience the same problem ? Does someone have an idea ?

Thanks for everything and have a nice day !
