Re: [etoys-notify] [JIRA] Commented: (SQ-1119) Rotating flaps DNU and other mishaps

Those are good commits. (I just pulled them down to my image.)

> There are still several issues with flaps and rotation.

Yes, but they are harder to invoke :) (I just locked up my image,
preceded by two DNUs, by dragging the rotation handle of the About
FlapTab.)

Have fun! David

p.s. impressed by the archaeology to track down the Squeak versions. A
binary search?

p.p.s. One of the walkbacks from the DNUs follows. Probably not very
helpful, though I suspect another case of not walking up the owner
chain correctly:

I was right, my earlier walkback wasn't relevant. The proximal
walkback (below) shows TransformationMorph with fullBounds as nil
again.

With enough time, I will figure out how to use haltOnlyOnce and get to
the bottom of this, though I have no objection to Karl or a.n.other
getting there first.

Have fun! David
