Using my standard bible (the "Einheitsübersetzung" and link set A, Power Lookup scrolls with the bible. 
Using the Clementine Vulgate, first it shows nothing:
    
        
            
    
Only after picking manually the verse and clicking on Power Lookup, the latter shows information:
    
        
            
    
This renders reading on quite impossible (when I have to select each verse single-handed).
