didn't see a fix posted yet so I just want to add if you are having trouble with your g keys not working and have windows vista disable the user account control and voila! works beautifully (took me a week of pulling my hair out to figure this out) was driving me nuts i use g1-g8 for single push team member targeting (highly useful for fast switching for healing/buffing) now that I finally got it working again back to leveling toons!
hope this helps some of you others that were having issues with this killer keyboard.
