I believe that this is the designed behavior.  The reason for it is to  
prevent moving units from "picking up" any other units that they move  
over top of.  So only the top unit(s) stay selected.  If you observe  
closely, you should see that although the units snap together for  
stacking, only the original moving units are selected.

To pick up the stack, you shouldn't have to select another map  
window.  You will just need to make sure you select the entire stack.
You can do this in one of several ways:
   1. Dragging a rectangle around the entire stack
   2. Clicking on a blank part of the map to deselect the unit and  
then clicking on the stack
   3. Double-clicking to open the stack and then selecting additional  
units (with shift-click)
