OS X 10.4 - Microsoft keyboard multimedia keys stopped working

Question

I have a Mac Mini running OS X 10.4. I've had a Microsoft wireless keyboard and mouse combo working with this machine for a year or two. Recently the multimedia keys on the keyboard have stopped working.

I've checked the settings under "Microsoft Keyboard" in System Preferences and everything seems to be configured correctly. I can't think of anything that has changed recently that might have caused this problem (except perhaps the upgrade to iTunes 9?).

The keyboard is a "Microsoft Wireless Multimedia Keyboard 1.1" according to the sticker on the bottom.

Any ideas?

Edit: I've plugged the keyboard into my laptop running Windows XP and the multimedia keys work fine there so the hardware is not defective.

Answer 1

I've installed the latest version of IntelliType Pro from the Microsoft website and, after rebooting, the keys are working again now. Not sure what caused them to stop working in the first place.
