I recently purchased the Microsoft Wireless Comfort Keyboard, and was very interested in the Zoom Slider feature. I have been unable to get it to work. I am using Intellitype 5.2 on WinXP, and all other features work perfectly, but when I attempt to use the Zoom feature, the CPU beeps once, and nothing happens. Any ideas on how to get it working?
