BootCamp 2.1 - Brightness issue (MacPro - Apple Cinema HD Display)

After updating BootCamp Services from 2.02 to 2.1, I have to face an issue with brightness of my screen.

BootCamp 2.1 sets the brightness to the minimum value (very difficult to work with) and I didn't find any option (in windows) to revert brightness to the initial value (max). Brightness +/- function keys (F1/F2 alu keyboard) do not operate.

When switching to MacOSX, the display brightness is also at the minimum value but I can revert it back to the max value. Then switching back to Windows... brightness is at the max value during the boot process and then is reduced at the minimum as soon as the boot camp services are loaded !...

I removed BootCamp Services 2.1 and reinstalled BootCamp Services 2.02... no brightness issue. Then updated again to 2.1 and got that problem back.

Anyone having to face that issue?

My config:
MacPro (Early 2008)
Apple Cinema HD Display (through Apple ADC-DVI adaptor)
Windows Vista Ultimate 64 bits

Thanks in advance for your feedback

Mac OS X (10.5)
