Thanks for the replies

So simply CapsLock can be the issue?

(I hope this is it by me and I didn't discover it

)
Because I haven't had this problem never before, I don't think a reinstall can't solve my problem.
I think I first gonna try this issue with the CapsLock on > switch OFF and see what it does

Maybe I change a setting on my pc (like I did also on another pc): when I set CapsLock on, I hear a "sound"

.
I let you all know if my problem is gone or not
