It sounds as if you are experiencing some sort of drag-and-drop behavior. Do you get any visual indication that the hand is picking up something when this happens? 

While the precise structure of the pictures you sent is not totally clear (is that 3 UIWindows on the left and 1 on the right?), you might try an experiment to verify this. 

1. Get the windows arranged in the "normal" positions.
2. In HandMorph>>dropMorphsEvent:, just after the line

			morphToDrop justDroppedInto: newOwner event: evt.


	self halt.

and accept it.
3. Try to generate the error. If you get to the halt, then we may able to tell what was being dropped into what. This will help us understand how it came about and how to fix it.

Note: after making the change in step 2, you won't want to save your image and it will be difficult to pick up anything without getting another halt.
