I'm using Windows 7 Ultimate and I'm trying to install a Microsoft IntelliType Pro keyboard and IntelliPoint mouse. The mouse installed fine and works well, however I'm having trouble with the keyboard. The computer detects it and apparently install it OK. It gives me a code to type in on the keyboard and that works fine. However, when it's done, the keyboard won't work. After a few minutes the icon for it disappears from my Bluetooth Devices folder, leaving only the mouse one. Please can someone suggest how to get it working?
