Master Schedule & 1 'inserted' subproject

[Marie]

When I open the master schedule it automatically opens
the subproject - as it should. However, I note that a
number of tasks appear multiple times straight under each
other - one task has the correct predecessors /
successors but the others have a predecessor back to the
one above and they appear in grey text not black. I have
deleted them but note that other appear throughout the
schedule each time I open it.
Does anybody know what they are or how they are caused?
and what I can do to prevent them from happening? Is
there a 'version control' available as part of Project
2000?

Hello Marie,
<<grey text not black>> : it's obviously any external predecessors or
external successors. Somebody created interprojet links : for example, the
end of a task in a project drives the begining of another task in another
projet.
You can manage the display of such external links by :
Tools / Options / View / Show external successors....
