Holding shift - clicking noise then disabled keyboard

I was just trying to roll a map, holding shift while I rolled it. I started hearing a clicking noise that I haven't heard in Windows or any other program before so I stopped but kept shift held down. The clicking started increasing in rate every few clicks for several seconds and then stopped. After that, any key I pressed on the keyboard would only result in a single click with no response. My first thought was fucking Windows stickykeys but alt-tab wouldn't work, ctrl-alt-delete wouldn't work, nothing. The only thing that worked was the mouse. I couldn't get to the Escape menu with the mouse however so the only way I could get away from the client and back to Windows was to go through the Shop and click Buy Points to open the browser window. At that point the problem went away like it never existed.

That is kind of troubling. Is the client doing any thing shady with macro detection or something that could potentially hijack an input device?

You are enabling a windows feature by holding shift for 8/10 seconds to enable sticky keys.

It's not a bug with the game, it would have happened on any other game(did it for me in a different one until i disabled it)

Read my post again, it was not stickykeys. Stickykeys will open a Windows settings window and still allow you to alt-tab. Furthermore, the clicking sound was not a stickykeys clicking sound. This was something local to the client that blocked my keyboard inputs until I was able to navigate out of the client using the only method it would allow using just a mouse.

Also, I have Stickykeys permanently disabled. It's not Stickykeys.

Also, it's not Stickykeys.

It's not Stickykeys.
