Hello. I have a Lenovo IdeaCentre 27" A730-57320990 All-in-One Computer running Windows 8.1. I have a problem with the touchscreen KEYBOARD that that won't work anymore with one exception. When the computer boots and the screen comes up to enter my password, the touchscreen keyboard does come up and let me enter my password. However, once it loads Windows 8.1 all the way, if I click on the keyboard in the lower right corner to enter text into any program, it will bring the keyboard up but it "freezes" and won't let me enter anything. I have to go to task manager and "end process" to close it down. The touchscreen itself works just fine to navigate etc, but it's just the touchscreen keyboard that doesn't anymore. I have searched and searched, but cannot find an answer for this problem. I hope you can help. Thank you.
