WOW, that is amazing to me. When even a Windows user isn't safe from a debacle such as that. Good job SWARF on finding that information. Just goes to show Windows isn't the answer for everything.
And Michel, I am really sorry dude. Things should just work. But, if it does work with the trackpad enabled, then it gives me an idea. What if you were go go inside your notebook, and disconnect the trackpad at the wire? Yes, I did just give you a brilliant beyond brilliant idea, you can thank me later.
If this works, that will most certainly solve the problem. Good luck!
