I guess there's a bit of misunderstanding about the scripts. They should 
contain only the code that you want to run after loading versions defined 
by the current Monticello Configuration (.mcm file). So if you just want 
to update the docking bar, then remove everything else (e.g. you don't 
want to initialize and reset SystemProgressMorph). So it should be:

TheWorldMainDockingBar updateInstances.
