Photoshop Shortcut from Xnview Classic

[Gummo]

I'm busy sorting scaling issues now that I have a new 32 inch 4K monitor. My problem is that, when I open Photoshop CS6 via its own shortcut, all is well. However, if when viewing an image on Xnview Classic, I hit the custom button to open it in Photoshop, the scaling is ignored - you can see the result in the screenshots.

Please advise.
