The keyboard now frequently messes up. When I try to type a letter, it performs some other random function. Every key stroke performs a function rather than typing the desired letter or number. Press enter and the window closes; press the space bar and the page minimizes, press d and something else happens. The keys also frequently double type or don't type at all. It's not consistent so I can't trace the problem to any one thing. The only way to correct it is to do a restart. I notice this has been brought up as a topic by others but not answered satisfactorily. It does seem to be an 8.1 problem so it needs to be addressed properly. Please advise how this can be fixed.
Another frequent problem is black strips appearing across web pages when I press a key. It only disappears when I click in the scroll bar.
8.1 has proved to be a nightmare and if I could uninstall it easily I would.
