However, e.g. RectTracker does not work as is with my Wacom tablet. The specific pen support (I just posted) is simply required for it to work. (I'm now under impression that RectTracker works with your tablet perfectly without these changes... ?? Perhaps XP-PEN drivers can avoids Windows Ink and work more mouse-like through the stack.)

Sorry, I might get lost in the code that we exchange here a lot...

Do you mean that my variant where Pen returns false and RectTracker is called in normal LeftDown does not work with Wacom? (My impression so far was that you are only testing RectTracker in Pen virtual method).

If so, does it mean RectTracker does not work even in pre-Pen U++? (With Wacom in "mouse mode")

bool Pen(Point p, const PenInfo& pn, dword keyflags) override {
		if(keyflags & K_SHIFT)
			return false;
		if(pn.pressure) {
			if((!!pn.pressure == !!pen.pressure) && drawing.GetCount())
				drawing.Top().Add(MakeTuple(pn.pressure, p));
			else
				drawing.Add().Add(MakeTuple(pn.pressure, p));
		}
		pen = pn;
		Refresh();
		return true;
	}
	
	void LeftDown(Point p, dword keyflags) override {
		if(keyflags & K_SHIFT) {
			RectTracker tracker(*this);
			tracker.MinSize(Size(-100000,-100000));
			tracker.Track(Rect(p,p));
		}
