Well, it sort of did and sort of didn’t. It certainly removed the appearance of the fake-cursor jumping around due to spurious mouse-leaves. But unfortunately it *crushed* performance and made painting horribly slow. A Tally implied some horrible volume of draw related messages that don’t happen normally. Sigh.

So right now I’m wondering if I can make the HandMorph’s temporaryCursor be some variety of form/morph that does the gridding while displaying. The issue there is that all the relevant code expects the temporaryCursor to be an image, so a lot would need fiddling with.

I guess another option might be to subclass HandMorph to try out adding more instvars and add gridding that way. At least that might avoid breaking everyone else’s Hands. ;-)
