Not working RCtrl+1. What is the reason?

Found that FAR stopped working RCtrl+1 and RCtrl+2, RCtrl+3and PR — work.
On the list checked out a few programs do not work.
Replacement keyboard (USB) — not working.
ShortCutToText( ShortCut( Key, Shift )) gives Ctrl+Ctrl (x11) instead of Ctrl+1 (x31).
What is the reason?

Add. So how to find the walk you through the process involved in intercepting considered unsportsmanlike, make sure the interception is carried out:

@Leonel_Howell, it's possible that a program intercepts of depression? You can try to kill all extraneous processes and to look at. - ryley11 commented on March 19th 20 at 09:25

Could be a software problem. For example - what is the application intercepts the keystrokes (keyboard hook) and incorrectly reports the event handling further. In this case, you need to remove everything from startup and after a reboot to kill all unneeded applications through the task Manager. To check it out.
I guess that's the program. There are two candidates: today's update Office 2019 and Opera. - Leonel_Howell commented on March 19th 20 at 09:24
