How stop Whonix "Operation Execution"confirmation pop-up?

[Darter]

I accidentally said yes to a request so now...

Every time I start/stop a Whonix AppVM, a popup window asks:

[Dom0] Operation execution

Do you want to allow the following operation?

Select the target domain and confirm with 'ok'

Source: a Whonix AppVM

Operation: NewStatus+     shutdown

Target: a list to select any AppVM

How do I stop this happening?
