Hi Peter, Unfortunately, you do not indicate which version of ROOT you are using. It is likely that you use an old version. We fixed a problem a few months ago when loading a new file in a chain. The branch addresses were not always recomputed. Please move to version 3.05/05 in case you use an older version.
