XnView Software

When I open an image in windows explorer, it directly goes to full screen mode. That's great.
But when I press Esc, I return to view mode rather than close XnView MP. I need to press Esc again to close XnView MP.
Is there any way to close XnView MP directly from full screen mode?
Thanks.

do you have tried to change settings>Interface>Keyboard>ESC

succeeded when changing from "always" to "only in fullscreen."
many thanks.
