I have had a strange problem.
Occasionally after switching to the lock screen(Win + L), I am not able to type the letter "O" or "L".
If my password contains either one of these letters, I am not able to log in unless I use the onscreen keyboard.

Anyone has encountered similar problem or found a solution?

Thanks in advance.

p/s I'm sorry admin this is a repost from other thread, tot this could be a better place to find a solution.
