I am using a Logitech S530 wireless keyboard. After applying the update, I lost the eject button functionality. Instead of ejecting, the CD tray, Dashboard was immediately launched. I should note that I have two external firewire CD/DVD drives hooked up to my computer and am running OS 10.4.10 (G5 2.3 dual processor tower with 2GB of RAM). I did an uninstall of the previous version prior to installing 2.2.2. After discovering the glitch, I also tried repairing permissions, and trashing the plist files. That didn't solve the problem. I remapped the Dashboard key from F12 to F7. That stopped Dashboard from launching when the eject button was pressed but the eject button still wouldn't eject the tray. I uninstalled 2.2.2 and reverted back the the previous version. Everything works fine now. My advise, hold off on this update.
