After being intermittently locked, my main keyboard is functioning fine - for now. Thank you again Berny for your help. Now to clarify, I thought I disabled the on-screen keyboard (as advised). Now I am not so sure I did that. Specifically, I have un-ticked the “Enable Secure Keyboard Input” - see attached PrintScr posted on this chat 1 day ago. In fact, On Screen Keyboard still appears selected - see PrintScr below. Just now I tried using Kaspersky On-Screen keyboard on my bank site; it functioned fine and did not lock my main keyboard. To muddy the waters further, late on the night of blocked main keyboard, MS has updated my Win10. I am not sure it had any beneficial effect. Thank you to everyone in this forum. A great help!
