Recently I have been unable to use any of the controls that are connected with the with the F1-F12 keys. I lost control of the backlight intensity, audio control, and num lock to be specific. I have a Macbook pro with leopard and the only thing that I had done software wise was I put USB overdrive for a optical mouse that I have and did the recent system update that had a keyboard change. What does it sound like is wrong to you ? How do I fix it ?
