I've installed on my W1070 Packard Bell, running Windows Vista Home Premium
w/o SP1.
When I logon, I receive a tons of windows messages "HOTKEY ERROR",
complaining that something happens at an address ...
To stop this process I have to select the last error message and start hit
the space bar ( click the "OK" button ), up to the first error window is
closed.
A new window is displayed telling me the driver of the keyboard has stopped
functioning.
.... but ... the keys all function well, including the special ones ...
???!!!???
Now: HOW CAN I explain to my wife what she have to do?
She answered me: "... and You have spent a lot of money ( really!!!!!!! 200$
!!! ) just to have the possibility to play a game with this <BEEEEEP>
keyboard?"

Pls note that, before this keyboard I have purchased another Microsoft
wireless kb+mouse set ( 5000 ), that have still some (other) problems.

I have upgraded the driver to the last version available from Microsoft
Download. No result.

Have someone any idea?
Thanks in advance
