Hi Mike, sorry for the delay in answering... Well, I'm using actual stamps and the shifting occurs when no zoom is applied (only edge cutting to the page). 
Now I've tried to zoom the page when out of editing mode and the stamps seem not maintaining the exact position: the position changes apparently randomly when I change zoom size. 
If I try to put the zoom to an extremely high value, the page renders totally out of the display, and I can see only the stamp over a white background.
Hope this helps... 
Best regards. 

Marco
