|Summary||0001484: [Bug] Halos persist after object is dropped into trash with grab halo. (Which grabs its morph back out)|
This one is fun.
Get an object.
Call up halos for it.
Use the grab handle to move it over to the trash.
The trash makes its "got it" sound.
The object disappears and immediately reappears.
Now drop the grab handle so the object is over the trash and its halos are still pressent.
Now mousing on the object itself will put it in the trash and the halos will jump to mid-screen. If you pick up the grab handle the object will reappear.
Alternately if you pickup the brown move handle you will not see the object
but the brown handle will be constrained by a rectangle the exact size of the trash's scrapbook.
When the trash is retaining lost objects the deleted object regains an owner and a world. The halos are still focused on the object and adapt.
This is what makes trying to delete an object which you have "grabbed" so frustrating.
So fixing it becomes a question of whose responsibility is it to release the halos focus?
The trashMorph, the haloMorph?, or the morph itself when it responds to delete?
If you know the elegant answer to this riddle please jump in.

This turns out to be several problems.
And I think I have misinterpreted what grab morph is doing.
The misinterpretation stems from the fact that entering the TrashCanMorph sets the hand to visible: false.
The visible bool was meant to inform the hand whether it needed to draw itself or not.
No display was needed when the hdwe cursor is displaying itself. If the hand is dragging things around it needs to draw itself and its submorphsand visible is meant to be true.
But here it is being used (poorly) as a hack to disappear the hands contents.
The second bug is that the halo for the deleted object was not being removed when it was stashed into scraps.
I've uploaded the fixes for the first two bugs.
Cursor and object remain visible until object is put in trash.
The halos now get removed at the appropriate moment.
Even having fixed those to bugs, a third bug remains. Using the grab handle to move the object over the trash can changes the state of the trash twice leaving it mostly off. Why this is I still haven't found out.
