I have noticed at times I've selected two adjacent tri's at a time and said to myself, "now that's impossible." So perhaps I am making a small "drag" with the mouse. I'll check too.
Correction on an earlier statement of mine, I can often find a hot spot at a corner *opposite* the hypotenuse.
I've now one sided all but a few quads of my shape. It's getting easier towards the end 'cuz I can now approach the task from both the inside and the outside.
Blue side up,
Bob
