> As I said in other mail, all problem is attaching morphs to HandMorph.

As far as I remember this problem is bound with removing of Presenter. 
This may help:

PasteUpMorph >> acceptDroppingMorph: dropped event: evt

	| aMorph |
	aMorph _ dropped.
	super acceptDroppingMorph: aMorph event: evt.

	aMorph submorphsDo: [:m | (m isKindOf: HaloMorph) ifTrue: [m
delete]].
