I wonder if it's the kooky resolution I'm running it at that throws MF2 off (1280x800, I've a widescreen display). I notice that in Knytt and Knytt Stories that using full screen mode it resizes my display to 640x350, but Saira stays at 1280x800. Perhaps Full Screen mode in Saira could resize the user's display in a similar way (possibly a choice of resolutions in the settings.exe ?)
