I tried that and it didn't work.....I also removed the batteries and everything. I went to their website after posting my problem and found drivers for the keyboard and decided to download them. They were created on November 20th which is newer than the June/July installers on the CD that came with it. I uninstalled the CD version and installed the version I downloaded and restarted and the control pane recognized the peripherals. I was amazed. I was able to configure ALL the keys. I didn't like that the F keys on the standard Apple keyboard couldn't be used, at least as far as I knew. Well this allows me to control iTunes from a keyboard which is a little easier than shuffling through a screen. It also has a ton of shortcuts available to open the hard drive, music folder, pictures, webcam (if you have one, which I don't), e-mail, web browser, instant messaging program....and it even has a scroll wheel on the keyboard if your so you don't need to grab the mouse to scroll down when your typing a big forum reply that goes below the window, or browsing PDF files, or whatever you might do. And best of all I was able to control iTunes from the couch downstairs, which means I had full control of the computer even though there was a floor/ceiling/desk between me and the screen. I personally thought it was amazing. So if anyone does experience the problem I had, try drivers off their website. I'm running OS X 10.2.3 and for some reason the CDs drivers didn't want to work right.
