What version of OCS are you using? If it's not the most recent, you may find that the problem is fixed with a combination of the most recent release plus the recommended patches for that version, though I can't promise it without investigating more closely.
Is your primary concern about non-editorial users running into the same problem? If so, that won't be the case, because the notifications you're seeing are targeted at directors, not end users.
What is the status of that presentation -- is it published on the public facing website, or somewhere in the editorial process?
