Problem with custom keyboard layout (QWERTY Mac) in Cubase 8

I’m using a Mac keyboard with my PC (running windows 7).

I’m using the QWERTY keyboard (not QWERTZ), so I remapped the Y and Z keys (and some others) creating a custom layout, using Microsoft Keyboard Layout Creator.

The problem is that Cubase doesn’t understand that I “switched” keys Z and Y, so the combo for Undo is Ctrl+Y, which is pretty annoying.

All the other apps understand the custom layout, only Cubase doesn’t get it.
