MS Natural Multi-Media Keyboard

I am running Vista Home Premium 64bit and I have a Microsoft Natural
Multi-Media Keyboard with the latest MS 64bit driver installed.
Everything works fine except the multi-media buttons don't work. They
do work if I click on the Microsoft Keyboard icon to bring up the
keyboard properties. As soon as I close the Keyboard Properties they
stop working.

I have a Logitech mouse and I see that their program Setpoint has a
tab in the Keyboard properties. I wonder if the two programs are
conflicting with eachother?
