So, Windows (as usual) wants to be its own boss; all others can play nice under a common boss for all Windows cares. Why am I not surprised... Yup, got the ("OEM" or not? Gotta check) W10 Pro license precisely because I'd gathered that there are limitations like this.

Tried Devuan in a Virtual Box on this (work) machine once; some VB extensions or something were missing, so it couldn't go above some stone-age resolution, 800x600 or at the most 1024x768 or something... Tiny postage stamp in the center of the screen. Gotta do better on my little red beauty.

Thanks!
