[squeak-dev] how to attachMorph: at the corner?

Interesting.  I guess I thought that wouldn't work because it was
"locked" to the hand based on its 'targetOffset' or something..

Thanks a lot.  Although it seems to work there's one strange anomaly.
For background, the action that causes #openInHand to be invoked is by
the user left clicking on a button.  In your example, which is not
invoked by a left click, the morph stays attached to the hand until I
click it down.  With my openInHand: hack it seemed it would also stay
attached without needing to hold down left button.  Very strange.

Morphic is hard stuff.
