full laptop keyboard doesn't work properly under vista

Hi everyone,

So I've got my new Fujitsu-Siemens Amilo Xi 1526 notebook with 17"
screen and thus a full keyboard with separate numeric keypad. The
'normal' keys work fine, but when it comes to the numeric keypad I get
all weird things. For instance, when I press the '2' key i get 'dsq',
when I press the '/' key i get 'cxw963', etc... These thing vary a
little with numlock on or off, but in both cases I get very weird
things on the screen...
As I said, all other keys work ine, except for the right-arrow key,
that gives .*- when pressed.

I've tried to updatethe driver, to change keyboard and language
settinge and some other thing, but nothing seems to work. Also,
Fujitsu-Siemens doesn't have a driver for the keyboard on their
website or the supplied dvd...

Does anyone have a clue what I can do to solve thisvery annoying
problem?

Thanks!!!
