After installing Windows 8 over Windows 7 on a Dell computer all worked well except for the Logitech wireless keyboard. When the shifted number keys were struck they printed an ASCII letter rather than their normal character. I substituted a USB keyboard with the same result. I have found no way to make the shifted number keys work correctly on this computer with Windows 8 installed. After restoring Windows 7, all worked correctly again. Am I alone with this problem? Are there any suggestions as I would like to reinstall Windows 8.
