The shortcut button is not working well.

The shortcut button is not working well.
The method is to use the same shortcut as Photoshop and illustration.

+ :ctrl+space+click
- : ctrl+alt+space+click
move: space

I used it well until yesterday,
It's moving strangely from today.

Is it an update problem?
I'd like to receive your answer by e-mail.
